Span<Char>

Int32

Remarks

A PEM-encoded X.509 certificate collection will contain certificates where each certificate begins with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE-----, with the base64 encoded DER contents of the certificate between the PEM boundaries. Each certificate is separated by a single line-feed character.

          Certificates are encoded according to the IETF RFC 7468 "strict" encoding rules.
