A formally verified implementation of cryptographic algorithms using the SPARK programming language. For the complete library proofs of the absence of run-time errors are available. Some of its subprograms include proofs of partial correctness.
Tool for encrypting files using blowfish, aes, des or cast5,
File hashing with md5, sha and ripemd160,
compresssion with gzip, and a nice user interface.
Created using C++ with Qt framework, depends on QCA third-part Qt Library and OpenSSL.
yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron)
yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.
Pure managed C# implementation of well-known cryptographic hash functions such as SHA-family (SHA0, SHA1, SHA2), MD-family (MD2, MD4, MD5), RIPEMD, Tiger, Haval, Snefru and others.

This library provides two operations: one to wrap key data, and another to unwrap the key data. This code also includes a fairly comprehensive unit test library which ensures the implementation is verified against the vectors provided in RFC 3394.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.
You asked, we delivered! Auth0 is excited to expand our Free and Paid plans to include more options so you can focus on building, deploying, and scaling applications without having to worry about your security. Auth0 now, thank yourself later.
Botan is a C++ crypto library Note: all versions of botan served on sf are OBSOLETE AND NOT SUPPORTED IN ANY WAY. Go to http://botan.randombit.net for the latest stable/supported release.
Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer. The Connection object wraps all the socket methods and can therefore be use
it is about a GUI (Graphical User Interface ) program based on Qt4 library ,that hides data on a picture using differents method depending on picture format (BMP,JPG,PNG,...) (this is called Steganography) the data can be on any file format
Crypto.Net is a free and open cryptography library for C# and .Net. AES (Rijndeal), Twofish, Blowfish, RSA, Diffie-Hellman, SSL/TLS, X509-Certificate builder, stream cipher modes or a secure netowrk stream are only some features of this library.
For system user to take backup of any confidential file(it may be code/important document)as it may contain content not meant for the others to view or the system may crash.We will be securing the backup of selected files at regular intervals of time.
Open Legacy Storage Document: Generic Document Archiving on Disk and Network(using MINA) Framework in Java for huge number of docs(up to 2^192 documents), efficient(Java NIO), crypto, net transfert, web retrieve, J2EE and eMail archiving compatible.
A kind of encryption named "simple stream encrypt". The length of plaintext segment or the length of key is not limited, but must greater than zero. The lengths of every plaintext segment in a process don't require equivalency.
This is a library for easy accessing chip cards /smart cards via a chipcard reader. It currently works under Linux, FreeBSD and Windows. It is tested with Towitoko and Kobil readers.
Erinaceus is an esoteric two dimensional programming language which uses bitmaps as sourcecode. It is turing complete and able to modify itself. It has been created with the goal to create a language that can be hidden in pictures easily.
MpNT is a multi-precision number theory library that provides a base for building cryptographic applications. It may however be used in any domain where efficient integer, modular, and floating-point computations involving large numbers are required.
MUSASH provides a utility to digest text, file and a byte char. It also able to compare two files, compare file, text and char to a hash. It also allows user to search for a string that evaluates to a hash given. Supported algo: MD5, SHA1 and SHA2 family
