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
