Defined in:

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

Decode the fields in a public key encoded as an SSH string.

raw - Binary public key as described by RFC4253 section 6.6 wrapped in

an SSH string..

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.
