b64_encoded_size ()

Get the number of bytes needed to encode a memory block in format base64.

uint32_t
b64_encoded_size(const uint32_t data_size);

data_size

The original block size.

Return

Base64 size.

b64_decoded_size ()

Get the number of bytes needed to decode a block of memory in base64 format.

uint32_t
b64_decoded_size(const uint32_t data_size);

data_size

The block size encoded in base64.

Return

The size in bytes.

b64_encode ()

Encode a block of memory in base64.

uint32_t
b64_encode(const byte_t *data,
           const uint32_t size,
           char_t *base64);

data	The data block.
size	Block size.
base64	The buffer where to store the result.

Return

The size in bytes.

Remarks

The buffer base64 must be at least the size returned by b64_encoded_size.

b64_decode ()

Decodes a block base64.

uint32_t
b64_decode(const char_t *base64,
           const uint32_t size,
           byte_t *data);

base64	The base64 block.
size	Block size.
data	The buffer where to store the result.

Return

The size in bytes.

Remarks

The buffer data must be at least the size returned by b64_decoded_size.

b64_encode_from_stm ()

Create a base64 with the contents of an input stream.

String*
b64_encode_from_stm(Stream *stm);

stm	Input stream.

Return

Base64 text string.

b64_encode_from_file ()

Create a base64 with the contents of a file.

String*
b64_encode_from_file(const char_t *pathname,
                     ferror_t *error);

pathname	File path.
error	Error code file opening fails. It can be `NULL`.

Return

Base64 text string.

Remarks

Will return an empty string (not NULL) if it cannot open the file.

b64_encode_from_data ()

Create a base64 from an in-memory buffer.

String*
b64_encode_from_data(const byte_t *data,
                     const uint32_t size);

data	Data block.
size	Data block size.

Return

Base64 text string.

b64_decode_from_str ()

Decodes a text in base64.

Buffer*
b64_decode_from_str(const String *base64);

base64

Base64 string.

Return

Buffer with the result.

b64_decode_from_data ()

Decodes a text in base64.

Buffer*
b64_decode_from_data(const byte_t *data,
                     const uint32_t size);

data	Data buffer containing base64 text.
size	Size in bytes of `data`.

Return

Buffer with the result.
