See OpenXPKI::Random for details.

Parameters

• "length" Int - length in bytes.

  Please note that the returned string is Base64/Hex encoded an thus longer.

• "format" Str

  The default is to return the random data with Base64 encoding (base64). Set to hex for lowercase hex. Note, the binary flag is superior to the format flag.

• "binary" Bool
