Returns the serial number of the issuing certificate.
To verify the String signature, digest, an instance of OpenSSL::Digest, must be provided to re-compute the message digest of the original data, also a String. The return value is true if the signature is valid, false otherwise. A PKeyError is raised should errors occur. Any previous state of the Digest instance is irrelevant to the validation outcome, the digest instance is reset to its initial state during the operation.
data = 'Sign me!' digest = OpenSSL::Digest::SHA256.new pkey = OpenSSL::PKey::RSA.new(2048) signature = pkey.sign(digest, data) pub_key = pkey.public_key puts pub_key.verify(digest, signature, data) # => true
Indicates whether this DSA instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.
Verifies whether the signature is valid given the message digest input. It does so by validating sig using the public key of this DSA instance.
digest is a message digest of the original input data to be signed
sig is a DSA signature value
dsa = OpenSSL::PKey::DSA.new(2048) doc = "Sign me" digest = OpenSSL::Digest::SHA1.digest(doc) sig = dsa.syssign(digest) puts dsa.sysverify(digest, sig) # => true
Does this keypair contain a private key?
Checks that cert signature is made with PRIVversion of this PUBLIC ‘key’
Restore session state from the session’s FileStore file.
Returns the session state as a hash.
