!!! Overview The [{$pagename}] (or [Certificate Fingerprint]) field is computed from [Hash] from the [Cryptographic Hash Function] of the whole [Certificate] using the identified [Certificate Signature Algorithm]. [{$pagename}] field is generated at the time it was created by [Certificate Issuer]. The process is: * [Hash] from the [Cryptographic Hash Function] of the whole certificate using the identified [Certificate Signature Algorithm] * Raise this [Hash] to [Certificate Issuer]'s [Public Key] [Certificate Exponent] value * And then divide this by the [Certificate Issuer]'s [Public Key] [Certificate Modulus] value. we then only use the we get this "decrypted" signature. [Hash]%%sup [Certificate Issuer]'s [Public Key] [Certificate Exponent]%%/MOD([Certificate Issuer]'s [Public Key] [Certificate Modulus] value) \\ \\ Since the [Certificate Issuer]'s [Public Key] is available to all, for [Certificate Validation] we can perform these same steps and [calculate the value|Verifying Certificate Signatures]. The calculated value should match the value on the [Protocol Server]'s [Certificate]. !!
