Description

ViaThinkSoft Modular Crypt Format 1.0 performs a simple hash or HMAC operation. No key derivation function or iterations are performed.

Format:

$1.3.6.1.4.1.37476.3.0.1.1$a=<algo>,m=<mode>[,i=<iterations>]$<salt>$<hash>

where <algo> is any valid hash algorithm (name scheme of PHP hash_algos() preferred), e.g.

sha3-512
sha3-384
sha3-256
sha3-224
sha512
sha512/256
sha512/224
sha384
sha256
sha224
sha1
md5

Algos not supported (because they have their own MCF):

bcrypt [Standardized crypt identifier 2, 2a, 2x, 2y]
argon2i [Crypt identifier argon2i, not standardized]
argon2id [Crypt identifier argon2i, not standardized]

Valid <mode> :

sp = salt + password ps = password + salt sps = salt + password + salt shp = salt + Hash(password) hps = Hash(password) + salt shps = salt + Hash(password) + salt hmac = HMAC where salt is the keypbkdf2 = PBKDF2-HMAC (Additional param i= contains the number of iterations)

<iterations> can be omitted if 0. It is required for mode=pbkdf2. For sp/ps/sps/shp/hps/shps/hmac, it is optional.

Like most Crypt-hashes, <salt> and <hash> are Radix64 coded with alphabet ./0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz and no padding.

Specification VTS/WF Std. 4
