README

A create-token service.

use Jahuty\CreateToken\Create;

(new Create())(8);   // returns something like "12a8b53c"
(new Create())(16);  // returns something like "8ab5dfaef3d2c999"

Security

This library uses the random_bytes() PHP function. According to PHP's manual, the function generates cryptographically secure, psuedo-random, opaque tokens suitable for salts, keys, and initialization vectors.

Length

Keep in mind, length is important when creating an opaque token. To provide sufficient randomness, a token's length SHOULD equal the length of the hash function's output. For example, a token that's hashed via SHA-256 should be 64 characters long; a token that's hashed via SHA-512 should be 128 characters long; so on and so forth.
