Derive a key from a passphrase

  1. OctetString deriveKey(size_t output_len, string passphrase, const(ubyte)* salt, size_t salt_len, size_t iterations)
    interface PBKDF
    final const
    OctetString
    deriveKey
    (
    size_t output_len
    ,
    in string passphrase
    ,
    const(ubyte)* salt
    ,
    size_t salt_len

passphrase string

the password to derive the key from

salt const(ubyte)*

a randomly chosen salt

salt_len size_t

length of salt in bytes

iterations size_t
