I\'m trying to find a list of strings
that can be used a a crypto algorithm to fit into this function, replacing SHA256
.
crypto.cre
I checked all of the cipher strings and everything in my gist and these are the only algo's that work with cipher to create a HMAC.
MD5
SHA
SHA1
SHA256
SHA384
The learning here is that ciphers
and hashes
are different and use different algorithms. With node's crypto
use .getCiphers()
and .getHashes()
methods to return an array with the names of the supported ciphers
and hashes
respectively.
var crypto = require('crypto')
console.log(crypto.getCiphers())
console.log(crypto.getHashes())
Which logs the following ciphers:

SHA-256 is not a cipher, it is a hash algorithm. That is probably why you didn't find it in a list of ciphers. The same goes for MD5 and all the various SHA algorithms.
Indeed, a hash algorithm is exactly what you need for HMAC. If you want to construct a MAC based on a block cipher, you'll need to use some other construction, such as OMAC/CMAC, PMAC or CBC-MAC.
