TextualEncoding class

Textual encoding

Implementation of the "textual encoding" defined by RFC 7468. This format is a method of representing binary data as text.

As RFC 7468 puts it, "for reasons that basically boil down to non-coordination or inattention, many PKIX, PKCS, and CMS libraries implement a text-based encoding that is similar to -- but not identical with --- PEM encoding. The RFC 7468 specifies a textual encoding format that articulates the de facto rules that most implementations operate by."

This encoding begins with a line that says "-----BEGIN label-----" and ends with "-----END label-----" with base-64 encoded data between them.

Note: unlike the proprietary OpenSSH public key format or the RFC 4716 'SSH Public Key File Format", this format does not support a comment and/or headers.

Example

This example has "RSA PUBLIC KEY" as the label.
