receive, at a certificate authority authentication system, a request for a digital certificate, the request including a public key of a public-private key pair, an identification of a target certificate recipient, and untrusted certificate validation data;

verify a relationship between at least a first portion of the untrusted certificate validation data and the target certificate recipient to provide verified untrusted certificate validation data, wherein, to verify the relationship between the at least a first portion of the untrusted certificate validation data and the target certificate recipient, the computer-executable instructions further cause the computing system to automatically initiate a communication link using the at least a first portion of the untrusted certificate validation data;

following, or concurrently with, verifying the relationship between the at least a first portion of the untrusted certificate validation data and the target certificate recipient, compare a second portion of the untrusted certificate validation data or the verified untrusted certificate validation data with entity specific data of the target certificate recipient to provide trusted certificate validation data, wherein the entity specific data is obtained from a confirmation computing system;

compare the trusted certificate validation data with the verified untrusted certificate validation data;

based at least in part on an identification of a match between the trusted certificate validation data and the verified untrusted certificate validation data, authenticate the target certificate recipient; and

issue the requested digital certificate for the target certificate recipient.

9. The non-transitory computer-readable media of claim 8 , wherein the confirmation computing system is distinct from and unaffiliated with the target certificate recipient.

10. The non-transitory computer-readable media of claim 8 , wherein comparing the second portion of the untrusted certificate validation data or the verified untrusted certificate validation data with entity specific data of the target certificate recipient occurs only after verifying the relationship between the at least a first portion of the untrusted certificate validation data and the target certificate recipient.

11. The non-transitory computer-readable media of claim 8 , wherein, to automatically initiate the communication link, the computer-executable instructions further cause the computing system to cause initiation of a plurality of emails between the certificate authority authentication system and the target certificate recipient.

12. The non-transitory computer-readable media of claim 8 , wherein, to automatically initiate the communication link, the computer-executable instructions further cause the computing system to cause initiation of an automatically initiated telephone call between the certificate authority authentication system and the target certificate recipient.

13. A method for authenticating a target recipient for a digital certificate, the method comprising:

receiving, at a certificate authority authentication system, a request for a digital certificate from the target recipient, the request including a public key of a public-private key pair, an identification of the target recipient, and untrusted certificate validation data, the untrusted certificate validation data including contact information associated with the target recipient;

sending, from the certificate authority authentication system, a verification request message to the target recipient using the contact information of the untrusted certificate validation data, wherein the verification request message is sent to the target recipient to verify a relationship between at least the contact information of the untrusted certificate validation data and the target recipient to provide verified untrusted certificate validation data, wherein the certificate authority authentication system sends the verification request message before comparing the untrusted certificate validation data or the verified untrusted certificate validation data with entity specific data of the target recipient to provide trusted certificate validation data, wherein the entity specific data is obtained from a confirmation computing system;

receiving, at the certificate authority authentication system, a response to the verification request message; and

determining, based on the response, the verified untrusted certificate validation data.

14. The method of claim 13 further comprising:

obtaining, at the certificate authority authentication system, the entity specific data from the confirmation computing system;

comparing, with the certificate authority authentication system, the untrusted certificate validation data or the verified untrusted certificate validation data with the entity specific data of the target recipient to provide the trusted certificate validation data;
