verify

Decodes the signed message using the MessageVerifier's secret.

verifier = ActiveSupport::MessageVerifier.new 's3Krit'
signed_message = verifier.generate 'a private message'

verifier.verify(signed_message) # => 'a private message'

Raises InvalidSignature if the message was not signed with the same secret or was not Base64-encoded.

other_verifier = ActiveSupport::MessageVerifier.new 'd1ff3r3nt-s3Krit'
other_verifier.verify(signed_message) # => ActiveSupport::MessageVerifier::InvalidSignature
