base64

Base64 encoding and decoding helpers.

Classes

Name	Description
`Decoder`	Base64 decoder.
`Encoder`	Base64 encoder.

Functions

Return	Name	Description
`size_t`	`encodedBufferCapacity` `inline`	Returns a safe temporary buffer size for encoding up to `inputSize` bytes. Includes padding/newline slack so callers can reuse the same buffer for finalize().
`std::string`	`encode` `inline`	Encodes an STL byte container to a Base64 string.
`std::string`	`decode` `inline`	Decodes a Base64-encoded STL container to a binary string.

encodedBufferCapacity

inline

inline size_t encodedBufferCapacity(size_t inputSize, int lineLength)

Returns a safe temporary buffer size for encoding up to inputSize bytes. Includes padding/newline slack so callers can reuse the same buffer for finalize().

encode

inline

template<typename T> inline std::string encode(const T & bytes, int lineLength)

Encodes an STL byte container to a Base64 string.

Parameters

T Container type with a size() method and contiguous operator[].

Parameters

bytes Input data container.
lineLength Characters per line in the output (0 disables wrapping).

Returns

Base64-encoded string.

decode

inline

template<typename T> inline std::string decode(const T & bytes)

Decodes a Base64-encoded STL container to a binary string.

Parameters

T Container type with a size() method and contiguous operator[].

Parameters

bytes Input Base64 data container.

Returns

Decoded binary string.

Variables

Return	Name	Description
`constexpr int`	`BUFFER_SIZE`
`constexpr int`	`LINE_LENGTH`

BUFFER_SIZE

constexpr int BUFFER_SIZE = 16384

LINE_LENGTH

constexpr int LINE_LENGTH = 72
