Method: OpenSSL::PKey::RSA#public_decrypt

Defined in:
lib/openssl/pkey.rb

#public_decrypt(string, padding = PKCS1_PADDING) ⇒ Object

:call-seq:

rsa.public_decrypt(string)          -> String
rsa.public_decrypt(string, padding) -> String

Decrypt string, which has been encrypted with the private key, with the public key. padding defaults to PKCS1_PADDING which is known to be insecure but is kept for backwards compatibility.

Deprecated in version 3.0. Consider using PKey::PKey#sign_raw and PKey::PKey#verify_raw, and PKey::PKey#verify_recover instead.
