This adds two new member functions getAuthTag and setAuthTag that
are useful for AES-GCM encryption modes. Use getAuthTag after
Cipheriv.final, transmit the tag along with the data and use
Decipheriv.setAuthTag to have the encrypted data verified.
Previous behaviour was to drop to an openssl prompt
("Enter PEM pass phrase:") when supplying a private key with a
passphrase. This change adds a fourth, optional, paramter that
will be used as the passphrase.
To include this parameter in a backwards compatible way it was
necessary to expose the previously undocumented (and unexposed)
feature of being able to explitly setting the output encoding.
Commit f53441a added crypto.getCiphers() as a function that returns the
names of SSL ciphers.
Commit 14a6c4e then added crypto.getHashes(), which returns the names of
digest algorithms, but that creates a subtle inconsistency: the return
values of crypto.getHashes() are valid arguments to crypto.createHash()
but that is not true for crypto.getCiphers() - the returned values are
only valid for SSL/TLS functions.
Rectify that by adding tls.getCiphers() and making crypto.getCiphers()
return proper cipher names.
This is a flag to make it easier for users to upgrade through the
breaking crypto change, and easier for us to switch it back if it's a
problem.
Explicitly set default encoding to 'buffer' in other tests, in case it
ever changes back.
crypto: Hash and Hmac default to buffers
crypto: Move Cipher encoding logic to JS
crypto: Move Cipheriv encoding logic to JS
crypto: Move Decipher encoding logic to JS
crypto: Move Decipheriv into JS, default to buffers
crypto: Move Sign class to JS
crypto: Better encoding handling in Hash.update
crypto: Move Verify class to JS
crypto: Move DiffieHellman to JS, default to buffers
crypto: Move DiffieHellmanGroup to JS, default to buffers
