class OpenSSL::PKey::RSA
This class is originally defined in the OpenSSL
module. As needed, methods have been added to it by the Net::SSH
module for convenience in dealing with SSH functionality.
Public Instance Methods
ssh_do_sign(data, sig_alg = nil)

Returns the signature for the given data.
# File lib/net/ssh/transport/openssl.rb, line 77 def ssh_do_sign(data, sig_alg = nil) digester = if sig_alg == "rsa-sha2-512" OpenSSL::Digest::SHA512.new elsif sig_alg == "rsa-sha2-256" OpenSSL::Digest::SHA256.new else OpenSSL::Digest::SHA1.new end sign(digester, data) end
ssh_do_verify(sig, data, options = {})
click to toggle source
Verifies the given signature matches the given data.
# File lib/net/ssh/transport/openssl.rb, line 63 def ssh_do_verify(sig, data, options = {}) digester = if options[:host_key] == "rsa-sha2-512" OpenSSL::Digest::SHA512.new elsif options[:host_key] == "rsa-sha2-256" OpenSSL::Digest::SHA256.new else OpenSSL::Digest::SHA1.new end verify(digester, sig, data) end
ssh_type()

Returns “ssh-rsa”, which is the description of this key type used by the SSH2 protocol.
# File lib/net/ssh/transport/openssl.rb, line 51 def ssh_type "ssh-rsa" end
Also aliased as: ssh_signature_type
to_blob()
click to toggle source
Converts the key to a blob, according to the SSH2 protocol.
# File lib/net/ssh/transport/openssl.rb, line 58 def to_blob @blob ||= Net::SSH::Buffer.from(:string, ssh_type, :bignum, e, :bignum, n).to_s end
