63 | daniel-mar | 23 | 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. |
