Ramjet 0.3.6

• Fix: in RAR 5 volumes encrypted with -p (file names not encrypted),
  every file split across volumes failed its checksum although its data
  was correct. RAR tweaks only the last part's checksum.

Downloads:

• ramjet-0.3.6-linux-x86_64.tar.gz: static binary; all 123 extraction and 29 CLI checks pass on it
• ramjet-0.3.6-linux-aarch64.tar.gz: builds, not tested.
• ramjet-0.3.6-windows-x86_64.zip: tested under Wine only
• ramjet-0.3.6-darwin-x86_64.tar.gz: builds, never run on a Mac
• ramjet-0.3.6-darwin-aarch64.tar.gz: builds, never run on a Mac

Ramjet 0.3.5

• Checksums (CRC32, BLAKE2sp) and file writes run on a second thread for
  files of 1 MB and more, overlapping with decompression.

• BLAKE2s compression is unrolled: archives with BLAKE2 checksums test
  about 1.4x faster.

• Fix: RAR 3.x and 4.x archives with passwords of 29 or more characters
  did not decrypt. RAR hashes the password with a SHA-1 quirk that
  overwrites the password buffer once it passes 64 bytes; checked against
  archives made by RAR 3.00, 3.41, 3.50 and 4.20. (This is what the 0.3.0
  note about "RAR 3.0-3.4 encryption" actually was.)

Ramjet 0.3.1

Speed.

• RAR 2.9-4.x LZ decoding is about 2.3x faster: a 64 KB scratch buffer for
  rare filter code sat in the stack frame of the per-symbol function.
• PPMd decoding is about 1.4x faster (inlined model access, direct loads).
• RAR 5 and RAR 4 matches are copied 8 bytes at a time.

Source only. Binaries are published with the latest release.

Ramjet 0.3.0

Older archives.

• RAR 2.0 archives (unpack versions 20 and 26): every method, solid
  archives, multimedia audio compression, the RAR 2.0 cipher, old-style
  archive comments. Checked against archives made by RAR 2.50.
• RAR 1.5 archives (unpack version 15) and the RAR 1.5 cipher: implemented,
  but untested against real archives.
• Fix: a main header with an old-style comment was reported as damaged.

Known limitation: encrypted archives made by RAR 3.0–3.4 may not decrypt
(those versions derived keys slightly differently); RAR 3.5 and later work.

Source only. Binaries are published with the latest release.

Ramjet 0.2.0

Command line.

• Asks for a missing or wrong password on the terminal, without echo (-p
  asks up front, -p- never asks); up to three tries.
• Asks before overwriting: yes, no, all, never, rename, quit. -o+, -o-,
  -or (rename to name (1).ext) and -y decide up front. Without a
  terminal nothing waits for input and existing files are kept.
• Progress percentage for files over 4 MB on a terminal (-idp turns it off).
• Exit status by kind of failure: 3 damaged data, 6 open error, 7 bad command
  line, 10 no files matched, 11 password, and more (see --help).
• -x<mask> and -x@<file> excludes, @<file> name lists, -op<path>,
  -ad, -kb, -idq, -inul, lb bare listing, --help, --version.
• A summary line after testing or extracting; listings show local time.

Fixes:

• A single name after the archive selected nothing and became the
  destination; only an argument ending in / is a destination now.
• Skipping an existing file in a solid archive broke every later file; the
  skipped file is still decoded, into nothing.

Ramjet 0.1.0

First release: a clean-room RAR reader.

• RAR 5.0: every compression method, solid archives, delta and x86 filters,
  multi-volume sets, AES-256 for data and headers, CRC32 and BLAKE2sp.
• RAR 2.9–4.x: LZ, PPMd, the standard VM filters (x86, Itanium, delta, RGB,
  audio), solid archives, old and new volume naming, AES-128 for data and
  headers.
• Symbolic and hard links, file references, file versions, SFX archives,
  comments; times and permissions restored; extraction confined to the
  destination directory.
