Method: SSHData::Encoding#decode_public_key

Defined in:
lib/ssh_data/encoding.rb

#decode_public_key(raw, offset = 0, algo = nil) ⇒ Object

Decode the fields in a public key.

raw - Binary String public key as described by RFC4253 section 6.6. algo - String public key algorithm identifier (optional). offset - Integer number of bytes into raw at which we should start

reading.

Returns an Array containing a Hash describing the public key and the Integer number of bytes read.
