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, bool  is_chunked = true  )

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.
is_chunked	If true, terminate 72 character blocks with newline

Returns

Encoded Base64 data in byte stream or NULL if input data cannot be encoded.

void ACE_Base64::init ( void  )

staticprivate

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.

ACE_Byte ACE_Base64::member_

staticprivate

Alphabet used to check valid range of encoded input i.e member_[alphabet_[0..63]] = 1
