var chacha = ;
var cipher = chacha;var decipher = chacha;
Create a cipher object by passing it a 256 bit key and 96 bit nonce, API is identical to crypto.createCipheriv()/createDecipheriv in node >= 11 with a gcm mode, in other words, e.g.
cipher;// must be called before datavar tag = cipher;// must be called after finish or enddecipher;// must be called before datadecipher;// must be called before data
decipher with throw if you don't set a tag or the tag doesn't match. See the node docs for more info (the iv length for gcm is also 96 bit fyi).
var cipher = chacha;
The API is identical to a cipher/decipher object in node >= 10. Encryption and decryption are the same.
var hmac = chacha;
API is identical to an hmac in node, so it's a stream with update and digest methods.
A variant version of the aead that is compatible with boringssl.
var cipher = key nonce;var decipher = key nonce true;
The third parameter is whether it should decipher, otherwise identical to createCipher/createDecipher. Doesn't implement variable length tags.
