The function vts_password_hash() replaces password_hash()
24
and adds the ViaThinkSoft Modular Crypt Format 1.0 hash as well as
25
all hashes from password_hash() and crypt().
26
 
27
The function vts_password_verify() replaces password_verify().
28
 
58 daniel-mar 29
ViaThinkSoft Modular Crypt Format 1.0 performs a simple hash or HMAC operation.
30
No key derivation function or iterations are performed.
31
Format:
32
        $1.3.6.1.4.1.37476.3.0.1.1$a=<algo>,m=<mode>$<salt>$<hash>
33
where <algo> is any valid hash algorithm (name scheme of PHP hash_algos() preferred), e.g.
34
        sha3-512
35
        sha3-384
36
        sha3-256
37
        sha3-224
38
        sha512
39
        sha512/256
40
        sha512/224
41
        sha384
42
        sha256
43
        sha224
44
        sha1
45
        md5
46
Valid <mode> :
47
        sp = salt + password
48
        ps = password + salt
49
        sps = salt + password + salt
50
        hmac = HMAC (salt is the key)
65 daniel-mar 51
        pbkdf2 = PBKDF2 (Additional param i= contains the number of iterations)
60 daniel-mar 52
Like most Crypt-hashes, <salt> and <hash> are Radix64 coded
53
with alphabet './0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz' and no padding.
