What's Inside ––Begin (RSA) Public Key–– Files?
- lucgommans 3y agoThere are two styles of public key, both with Base64 between the boundaries: -----BEGIN RSA PUBLIC KEY----- -----END RSA PUBLIC KEY----- and -----BEGIN PUBLIC KEY----- -----END PUBLIC KEY----- The top answer gives a stellar explanation of internals in response to OP asking how to convert between them. For the former (older) format, there is this overview in the middle of the post: > [This is an] PEM DER ASN.1 PKCS#1 RSA Public key > - PEM: synonym for base64 > - DER: a flavor of ASN.1 encoding > - ASN.1: the binary encoding scheme used > - PKCS#1: The formal specification that dictates representing a public key as structure that consists of modulus followed by an exponent > - RSA public key: the public key algorithm being used Trivial! I really appreciated the explanation of all these terms in one place, even if I question that PEM really just means Base64 it is likely a useful simplification.
