kitearchive

Compression codecs, archive readers and a ZIP writer, in pure common Kotlin.

DEFLATE, gzip, zlib, LZ4 and Snappy behind one Codec interface; readers for ZIP (with ZIP64), TAR, ar and cpio behind ArchiveReader; CRC-32, CRC-32C, Adler-32, CRC-64/XZ and xxHash32; and a magic-byte format sniffer. Everything is ByteArray in, ByteArray out, with no I/O and no dependency beyond kotlin-stdlib.
