Overview#

Issuer Unique Identifier added in X509v2 to handle the possible reuse of Certificate Subject and/or Certificate Issuer names over time. Their use is deprecated by the IETF, so you shouldn't generate these in your certificates.

If you're writing certificate-handling code, just treat them as a blob which happens to be an encoded bitstring.

UniqueIdentifier ::= BITSTRING
