The Zlib
module supports the compression and decompression of data, using the zlib
library. The algorithm used is Lempel-Ziv compression as in the gzip
and zip
compressors. While compression itself is not encryption, it is often used prior to encryption to hide regularities in the plaintext, and reduce the size of the ciphertext.
val compress : ?level:int -> unit -> transform
Return a transform that compresses its input. The optional level
argument is an integer between 1 and 9 specifying how hard the transform should try to compress data: 1 is lowest but fastest compression, while 9 is highest but slowest compression. The default level is 6.
val uncompress : unit -> transform
Return a transform that compresses its input. The optional level
argument is an integer between 1 and 9 specifying how hard the transform should try to compress data: 1 is lowest but fastest compression, while 9 is highest but slowest compression. The default level is 6.
Return a transform that decompresses its input.
