Hi,

In the document binascii.b2a_base64(data) said the data length should less than 57.But I can use it for more than 57.Can you give me an explain?

import struct import binascii payload = struct.pack('>hhiii',4,0,0,0,0) payload = payload*10 len(payload) 160 binascii.b2a_base64(payload) 'AAQAAAAAAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAAAAAAABAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAAAAAAABAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAAAAAAABAAAAAAAAAAAAAAAAAAAAAQAAAAAAAAAAAAAAAAAAA==\n'

a = binascii.b2a_base64(payload)

...

...

len(a) 217

Hi Liying, the function itself can process arbitrary lengths. The documentation just states that if you want the *result* to be compatible to the base64 standard, the input should be <= 57 characters in length. cheers, Georg -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.21 (GNU/Linux) iEYEARECAAYFAlJRPmMACgkQN9GcIYhpnLDK9gCglvQZYDlpj+aCw3//PwxWOWyo pMoAnivHlRIPjlXuBDkfy/xGFdiGllKS =7eiH -----END PGP SIGNATURE-----
