Rsync friendly file encryption - A slightly reduced strength bulk encryption. In exchange for the reduced strength, you get the ability to rsync the encrypted files, so that local changes in the ... [More] plaintext file will result in (relatively) local changes to the cyphertext file. [Less]

As3 Crypto is a cryptography library written in Actionscript 3 that provides several common algorithms. This version also introduces a TLS engine (TLS is commonly known as SSL.) Protocols: TLS 1.0 ... [More] support (partial) Certificates: X.509 Certificate parsing and validation, built-in Root CAs. Public Key Encryption: RSA (encrypt/decrypt, sign/verify) Secret Key Encryption: AES, DES, 3DES, BlowFish, XTEA, RC4 Confidentiality Modes: ECB, CBC, CFB, CFB8, OFB, CTR Hashing Algorithms: MD2, MD5, SHA-1, SHA-224, SHA-256 Paddings available: PKCS#5, PKCS#1 type 1 and 2 Other Useful Stuff: HMAC, Random, TLS-PRF, some ASN-1/DER parsing The library is offered under the BSD license, and include several derivative works from Java, C and javascript sources. Check the LICENSE.txt file for a list of contributors. You can look at a demo of the functionality of the library. It's built with Flex 2. It includes a unit test tab, and a benchmark tab.

The scope of this project is to improve situational awareness about malicious crypto-code, cryptographic-viral binary protection methods, compression, detection, heuristics, emulation and evasion. The ... [More] research and proof of concept code should be used as a tool for anti virus vendors, reverse code engineers, developers, Government, forensics analysts, academics and students. The concept behind the code is to promote an idea of the need for change in our current anti virus and intrusion detection technology which we depend on to protect critical information. Malicious crypto code will become more prevalent in the near future and we must design new methods for detection and prevention. Thank you for taking interest in this project hopefully together we can improve the quality of anti virus technology. [Less]
