Base64 options
| Constant | Value | Description |
|---|---|---|
| Base64DecodingIgnoreUnknownCharacters | 1 |
Use the following option to modify the decoding algorithm so that it ignores unknown non-Base64 bytes, including line ending characters. |
| Base64Encoding64CharacterLineLength | 1 |
Line length limit should be 64. |
| Base64Encoding76CharacterLineLength | 2 |
Line length limit should be 76. |
| Base64EncodingEndLineWithCarriageReturn | 16 |
use CR as line ending instead of CRLF. |
| Base64EncodingEndLineWithLineFeed | 32 |
use LF as line ending instead of CRLF. |
Compression Algorithm
| Constant | Value | Description |
|---|---|---|
| CompressionAlgorithmLZ4 | 1 | LZ4 is appropriate if compression speed is critical. LZ4 generally sacrifices compression ratio in order to achieve its greater speed. more |
| CompressionAlgorithmLZFSE | 0 |
LZFSE is the recommended compression algorithm if you don't have a specific reason to use another algorithm. Note that LZFSE is intended for use with Apple devices only. This algorithm generally compresses better than Zlib, but not as well as LZMA. It is generally slower than LZ4. |
| CompressionAlgorithmLZMA | 2 | LZMA is appropriate if compression ratio is critical and memory usage and compression speed are not a factor. LZMA is an order of magnitude slower for both compression and decompression than other algorithms. It can also use a very large amount of memory, so if you need to compress large amounts of data on embedded devices with limited memory you should probably avoid LZMA. more |
| CompressionAlgorithmZlib | 3 | Zlib is appropriate if you want a good balance between compression speed and compression ratio, but only if you need interoperability with non-Apple platforms. Otherwise, LZFSE is generally a better choice than Zlib. more |
