node-steam-crypto
Node.js implementation of Steam crypto. All keys and data are passed as Buffers.
verifySignature(data, signature[, algorithm])
Verifies an RSA signature using the Steam system's public key. data
and signature
should both be Buffers. algorithm
defaults to "RSA-SHA1". Returns true
if the signature is valid, or false
if not.
generateSessionKey()
Generates a 32 byte random blob of data and encrypts it with RSA using the Steam system's public key. Returns an object with the following properties:
plain
- the generated session keyencrypted
- the encrypted session key
symmetricEncrypt(input, sessionKey)
Encrypts input
using sessionKey
and returns the result.
symmetricDecrypt(input, sessionKey)
Decrypts input
using sessionKey
and returns the result.
