46-3-301 Issuing a certificate. (1) (a) A licensed certification authority may issue a certificate to a subscriber only after all of the following conditions are satisfied: (i) the certification authority has received a signed request for issuance of a certificate by the prospective subscriber; (ii) the certification authority confirms that: (A) the prospective subscriber is the person identified in the request and the person to be identified in the certificate to be issued; (B) if the prospective subscriber is acting through an agent, the subscriber duly authorized the agent to have custody of the subscriber's private key and to request issuance of a certificate listing the corresponding public key; (C) the prospective subscriber bears a distinguished name; and (D) the prospective subscriber rightfully holds the private key corresponding to the public key to be listed in the certificate; (iii) the certification authority confirms that the prospective subscriber holds a key pair capable of: (A) affixing a digital signature by the private key corresponding to the public key to be listed in the certificate; and (B) verifying that a digital signature has been affixed by the corresponding private key through the use of the public key. (b) The requirements of this subsection may not be waived or disclaimed by the licensed certification authority or the subscriber. (2) (a) If a certificate is requested by an agent or an apparent agent of the subscriber, the certification authority may not issue the certificate until after the certification authority has given ten days' written notice to the prospective subscriber through all of its record leaders at its record address. (b) The notice shall express the certification authority's intent to issue a certificate for the prospective subscriber to the requesting agent and the date on which the certificate is to be issued. (c) The requirement of notice in this subsection may be waived or disclaimed only by: (i) a writing signed by all of the record leaders of the prospective subscriber; and (ii) confirmation of the authenticity of the waiver by the certification authority. (3) (a) If the subscriber accepts the certificate, the certification authority shall publish a signed copy of the certificate in the repository provided by the division or in one or more recognized repositories agreed upon by the certification authority and the subscriber named in the certificate. (b) The contract between the certification authority and the subscriber may provide that the certificate may not be published. (c) If the subscriber does not accept the certificate, a licensed certification authority may not publish the certificate in the repository provided by the division. (4) Nothing in this section precludes a licensed certification authority from conforming to standards, security policies, or contractual requirements more rigorous than, but consistent with, this section. (5) (a) If a licensed certification authority confirms that a certificate was not issued as required by this section, the certification authority: (i) shall immediately revoke the certificate; or (ii) may suspend the certificate while investigating to confirm grounds for revocation. (b) The certification authority shall give notice as soon as practicable to the subscriber of a certificate revoked or suspended pursuant to this subsection. (6) The division may order the licensed certification authority to suspend or revoke a certificate which the certification authority issued if, after notice and an opportunity for the certification authority and subscriber to be heard in accordance with the Administrative Procedures Act, the division determines that: (a) a certificate was issued without substantial compliance to this section; and (b) the noncompliance poses a significant hazard to parties relying on the certificate.
46-3-302 Representations by the subscriber accepting a certificate. (1) By accepting a certificate issued by a licensed certification authority, the subscriber identified in the certificate certifies to all who justifiably rely on the information contained in the certificate that: (a) each digital signature affixed by means of the private key corresponding to the public key listed in the certificate is a legally valid signature of the subscriber, unless the certificate: (i) is suspended; (ii) is revoked by the certification authority; or (iii) has expired; (b) no unauthorized person has access to the private key corresponding to the public key listed in the certificate; (c) all representations made by the subscriber to the certification authority which are material to information contained in the certificate are true; and (d) the information contained in the certificate is true. (2) By requesting on behalf of a principal the issuance of a certificate naming the principal as subscriber, a person certifies to all who justifiably rely on the information contained in the certificate that: (a) the person holds all authority legally required for issuance of a certificate naming the principal as subscriber; and (b) the person has authority to sign digitally on behalf of the principal, and, if that authority is limited in any way, safeguards exist to prevent a digital signature exceeding the bounds of the person's authority. (3) A person may not disclaim or rebut the representations implied in this section or obtain indemnity for them, if the effect of the disclaimer or indemnity is to limit liability for wrongful issuance of a certificate as against persons justifiably relying on the certificate. (4) (a) If a subscriber makes a false, material and written representation of fact, or fails to disclose a material fact, with either the intent to deceive the certification authority or a person relying on the certificate, or with negligence, the subscriber, by accepting a certificate, becomes obligated to indemnify the issuing certification authority for any loss or damage caused by the misrepresentation or negligence. (b) If the certification authority issued the certificate at the request of agents of the subscriber, both the agents and the subscriber shall indemnify the certification authority in accordance with this subsection. (c) The indemnity provided in this subsection may not be disclaimed or superseded by contract between the certification authority and the subscriber. (5) To obtain information required for issuance of a certificate, the certification authority may require a subscriber to testify under oath or an affirmation of truthfulness.
46-3-303 Control of the private key. (1) By accepting a certificate issued by a licensed certification authority, the subscriber identified in the certificate assumes a duty to exercise reasonable care in retaining control of the private key and keeping it confidential. (2) A private key is the property of the subscriber who rightfully holds it. (3) (a) If a certification authority holds the private key corresponding to a public key listed in a certificate which it issued, it holds the private key as a fiduciary of the subscriber named in the certificate, regardless of any provision to the contrary in a contract between the subscriber and the certification authority. (b) A certification authority holding the subscriber's private key may use it only upon the prior written consent of the subscriber.
46-3-304 Duties of a licensed certification authority in issuing a certificate. (1) (a) By issuing a certificate, a licensed certification authority warrants to the subscriber named in the certificate that: (i) the certificate contains no information known to the certification authority to be false; (ii) the certificate satisfies the requirements of this chapter and does not exceed any limitations of the certification authority's license; and (iii) the certification authority has not exceeded any limitation of its license in issuing the certificate. (b) The warranties described in this subsection may not be limited or disclaimed by contract. (2) Unless the parties otherwise agree, a certification authority, by issuing a certificate, promises to the subscriber: (a) to notify the subscriber within a reasonable time of any facts known to the certification authority which affect the validity or reliability of the certificate once it is issued; and (b) to act promptly to suspend or revoke a certificate in accordance with Section 46-3-305. (3) By issuing a certificate, a licensed certification authority certifies to all who justifiably rely on the information contained in the certificate that the certification authority has complied with all applicable requirements for issuance of the certificate. (4) By publishing a certificate, a licensed certification authority certifies to the repository and to all who justifiably rely on the information contained in the certificate that the certification authority has issued the certificate to the subscriber.
46-3-305 Suspension of a certificate. (1) (a) Unless the certification authority and the subscriber otherwise agree, the licensed certification authority which issued a certificate shall suspend the certificate for a period of 48 hours: (i) upon request by a person identifying himself as: (A) the subscriber named in the certificate; (B) an agent of the subscriber; (C) a business associate of the subscriber; (D) an employee of the subscriber; or (E) a member of the immediate family of the subscriber; or (ii) upon order of the division pursuant to Subsection 46-3-301(6). (b) The certification authority need not confirm the identity or division of the person requesting suspension. (2) (a) Unless the certificate or other records in the repository indicate otherwise, the division, a court clerk, or a county clerk may suspend a certificate issued by a licensed certification authority for a period of 48 hours, if: (i) a person identifying himself as the subscriber named in the certificate, or as an agent, business associate, employee, or member of the immediate family of the subscriber requests suspension; and (ii) the requester represents that the certification authority which issued the certificate is unavailable. (b) The division or clerk may: (i) require the requester to provide evidence of his identity, authorization, and the unavailability of the issuing certification authority; (ii) inquire of the contents of the certificate and the secret field described in Subsection 46-3-104(4); and (iii) decline to suspend the certificate with or without cause. (c) The division or law enforcement agencies may investigate multiple suspensions by the division, court clerk, or county clerks for possible wrongdoing. (3) (a) Immediately upon suspension of a certificate, the suspending certification authority, court clerk, or county clerk shall publish signed notice of the suspension in all repositories in which the certificate was published. (b) If the repository described in Subsection (a) no longer exists, or if the person suspending the certificate does not know all the repositories in which the certificate was published, the certification authority shall publish the notice of suspension in the repository provided by the division. (4) (a) A certification authority shall terminate the suspension of a certificate that was suspended by request if: (i) the subscriber named in the suspended certificate requests that the suspension be terminated and, the certification authority confirms the identity of the person making the request, and when the requester is acting as agent, the agent's authorization by the subscriber; or (ii) the certification authority discovers and confirms that the request for the suspension was made without authorization by the subscriber. (b) This subsection does not obligate the certification authority to confirm a request for suspension. (5) The contract between a subscriber and a licensed certification authority may: (a) limit or eliminate suspension by the certification authority upon request; or (b) provide for termination of a suspension or disclosure of information about a suspension that varies from the requirements of Subsections (1), (2), (4), and (5), except that if the contract varies from the requirements of this section, the certificate must indicate the differences for the contractual variation to be valid. (6) (a) No person may knowingly or intentionally misrepresent to a certification authority his identity, name, distinguished name, or authorization when requesting suspension of a certificate. (b) Violation of this subsection is a class B misdemeanor. (7) The subscriber is released from the duty to keep the private key secure pursuant to Section 46-3-303 during the period the certificate is suspended.

(3) (a) A licensed certification authority may revoke one or more certificates which it issued if the certificates are or become unreliable regardless of whether the subscriber consents to the revocation.
