Free pss software for linux

RSA-Haskell is a collection of command-line cryptography tools and a cryptography library written in Haskell. The project is intended to be useful to anyone who wants to secure files or communications or who wants to incorporate cryptography in their Haskell application.
The libraries include Haskell implementations of SHA1, EME-OAEP, EMSA-PSS, MGF, RSAES-OAEP, and RSA-PSS. These standards implement signature/verification, strong cryptography, and hashing.
Enhancements:
- Documentation is now available for the command line utilities.
- An easy-to-use Windows binary release is available.

- DEFLATE (RFC 1951) compression/decompression with gzip (RFC 1952) and zlib (RFC 1950) format support
- fast multi-precision integer (bignum) and polynomial operations, with SSE2 optimizations for Pentium 4 processors, and support for 64-bit CPUs
- finite field arithmetics, including GF(p) and GF(2^n)
- prime number generation and verification
- various miscellaneous modules such as base 64 coding and 32-bit CRC
- class wrappers for these operating system features (optional):
- high resolution timers on Windows, Unix, and MacOS
- Berkeley and Windows style sockets
- Windows named pipes
- /dev/random and /dev/urandom on Linux and FreeBSD
- Microsofts CryptGenRandom on Windows
- A high level interface for most of the above, using a filter/pipeline metaphor
- benchmarks and validation testing
- FIPS 140-2 Validated
Enhancements:
- This release added VMAC and Sosemanuk, and improved the speed of several other algorithms using x86/x86-64/MMX/SSE2 assembly.
- Random number generators and DSA-like signature algorithms were modified to reduce the risk of reusing random numbers and IVs after virtual machine state rollback.

.AudioLink is a tool that makes searching for music on your local storage media easier and faster. Your searches can include a variety of criteria, like male artists, female artists, band, genre, etc. It is flexible, you have options of using a command line interface, multiple choices of GUIs, designing your own search criteria, etc. The possibilities are endless.
Currently, its called AudioLink, cos the first milestone would just handle audio files... subsequent versions will be capable of searching for content in HTMLs, PDFs, PSs and other file formats.
This project started with my need of searching for files on my local machine, be it music or any stored information in .txt, .html, .pdf formats. The main goal of the software is to make searching for _content_ on local file systems (or remote file systems mounted in the local namespace) easier. This differs from other search tools, which look for files, not content. You cant use traditional tools like grep to search for songs or a particular artist, for example.
If you are in search of such a tool, AudioLink is the right choice for you for you!
The project will further be improved upon to include a LAN crawler, which will sniff on NFS, SMB, FTP, among other protocols, to collect information on the files residing on other machines as well.
Enhancements:
- * code/alsearch:
1. config file isnt perl code now; simple "a = b" stuff
2. command-line args override config file options
- code/alfilldb: ouch! one more ref. to alfilldb_usage code/alfilldb: removed ref. to alfilldb_usage.txt
- code/alfilldb:
- config file isnt perl code now; simple "a = b" stuff
- command-line args override config file options
- code/audiolink: 1. clean up the printed statements.
- added a verbose mode
- config file isnt perl code now; simple "a = b" stuff
- default to localhost for the host field
- command-line args override config file options
- cvsignore: ignore debian/ and gui/
- Documentation/alsearch_usage.txt, Documentation/alfilldb_usage.txt: remove the _usage.txt files; we now have *_doc.html files.
- INSTALL:
- You can now use the audiolink script to create the datbase and table.
- README: better 1st para
- TODO: 1. We have a config file
- Debian packaging is done; get rpms done now
