reallyme-codec-pem

reallyme-codec-pem parses and emits PEM text armor: BEGIN/END labels, base64 bodies, line ending normalization, strict label matching, and size limits.

This is a bounded PEM armor profile rather than a strict RFC 7468 generator or parser. Encoding defaults to 64-character body lines but accepts an explicit width from 1 through 76. Decoding joins base64 body lines of any width and permits empty lines; boundary lines must match exactly, without trailing whitespace. Callers that require strict RFC 7468 input should enforce that profile before passing armor to this crate.

It deliberately does not interpret DER, ASN.1, or key structure. Use this crate when you need the text envelope only. Algorithm-aware key import belongs in the crypto layer that consumes the decoded bytes.
