local b64 = require'libb64'

FFI binding of libb64, a fast base64 encoder and decoder by Chris Venter.

b64.encode(s[, size]) -> s
b64.decode(s[, size]) -> s
b64.encode(cdata, size) -> s
b64.decode(cdata, size) -> s

Encode/decode a string or cdata to a string.

b64.encode_tobuffer(s, [size], out_buf, out_size) -> bytes_written
b64.decode_tobuffer(s, [size], out_buf, out_size) -> bytes_written
b64.encode_tobuffer(cdata, size, out_buf, out_size) -> bytes_written
b64.decode_tobuffer(cdata, size, out_buf, out_size) -> bytes_written

Encode/decode a string or cdata to a buffer.

• encoding needs a buffer of at least size * 2 + 3 bytes
• decoding needs a buffer of at least math.floor(size * 3 / 4) bytes

TODO

Stream-like interface similar to zlib's inflate/deflate.
Benchmark against this pure ffi implementation1.
