Error code: sec_error_reused_issuer_and_serial

06 November 2014

I saw the error Error code: sec_error_reused_issuer_and_serial in FireFox when messing with SSL Certificates. I resolved this by deleting the cert.db e.g. C:\Users\colinw\AppData\Roaming\Mozilla\Firefox\Profiles\qz5nj3y9.default\cert8.db.

I was recreating certificates via a script using the same subject names but with different hashes which upsets previous certificate exceptions I have made.
