ssl:load_public

load_public_key(+Stream, -PublicKey) is det: Load a public key PublicKey from the given stream Stream. Supports loading both DER- and PEM-encoded keys. The key must be an RSA or EC key. DH and DSA keys are not supported, and PublicKey will be bound to an atom (dh_key or dsa_key) if you try and load such a key. Otherwise PublicKey will be unified with public_key(KeyTerm) where KeyTerm is an rsa/8 term representing an RSA key, or ec/3 for EC keys.
