VMProtect v3.9.4 WebLM Encryption Algorithm

[target]

key = rand bytes // In fact, this is a salt, which is a randomly generated eight bytes.
hwid = vmp hwid bytes
modulus = rsa modulus bytes
// Please do not use sha1.hexdigits here, keep it in its original byte form.
hash = sha1.digits(key + hwid + modulus)
decrypt_key = sha1.digits(key + modulus) // This key is used to decrypt the license returned by weblm.
