Detailed Description

(C) 2018 Jack Lloyd

Botan is released under the Simplified BSD License (see license.txt)

Ordinary applications should never need to include or use this header. It is exposed only for specialized applications which want to implement new versions of public key crypto without merging them as changes to the library. One actual example of such usage is an application which creates RSA signatures using a custom TPM library. Unless you're doing something like that, you don't need anything here. Instead use pubkey.h which wraps these types safely and provides a stable application-oriented API.

	)

Perform encoding using the base provided

Parameters

base	object giving access to the encodings specifications
output	an array of at least base.encode_max_output bytes
input	is some binary data
input_length	length of input in bytes
input_consumed	is an output parameter which says how many bytes of input were actually consumed. If less than input_length, then the range input[consumed:length] should be passed in later along with more input.
final_inputs	true iff this is the last input, in which case padding chars will be applied if needed

Returns

number of bytes written to output
