Detailed Description

Encode/Decode a stream of bytes according to Base64 encoding.

This class provides methods to encode or decode a stream of bytes to/from Base64 encoding. It doesn't convert the input stream to a canonical form before encoding.

Member Function Documentation

ACE_Byte * ACE_Base64::decode const ACE_Byte input,
size_t *  output_len
[static]
 

Decodes a stream of Base64 to bytes data

Parameters:
input Encoded Base64 data in byte stream.
output_len Length of the binary byte stream.
Returns:
Binary data in byte stream or NULL if input data cannot be encoded.

ACE_Byte * ACE_Base64::encode const ACE_Byte input,
const size_t  input_len,
size_t *  output_len
[static]
 

Encodes a stream of bytes to Base64 data

Parameters:
input Binary data in byte stream.
input_len Length of the byte stream.
output_len Length of the encoded Base64 byte stream.
Returns:
Encoded Base64 data in byte stream or NULL if input data cannot be encoded.

void ACE_Base64::init  )  [static, private]
 

Initialize the tables for encoding/decoding.

size_t ACE_Base64::length const ACE_Byte input  )  [static]
 

Return the length of the encoded input data

Parameters:
input Encoded Base64 data in byte stream.
Returns:
Length of the encoded Base64 data.
