KDF() function

    XMLWordPrintable

Details

    Description

      A key derivation function, with the same result as EVP_KDF_derive() of OpenSSL.
      Something like

      KDF(key_str, salt [, {info | iterations} [, kdf_name [, width ]]])

      kdf_name could be one of "pbkdf2_hmac" (default) or "hkdf". The latter always returns NULL if built with OpenSSL 1.0 (default on CentOS 7 and SLES 12).

      width is in bits, can be any positive number divisible by 8.
      if the width is not specified, it's taken from the @@block_encyption_mode
