OpenSSLWith the Open SSL 0. 9. 7c library, developers can write applications that take advantage of Secure Sockets Layer (SSL v2/v3), Transport Layer Security (TLS v1), and a full-strength general-purpose cryptography library. Security features such as data integrity, authenticity, and privacy can be implemented. To compile for Win32, Perl or compiling under Cygwin is required. Some of the encryption routines/algorithms are covered by patents. Download OpenSSL (2.81 Mb) cryptlibA security toolkit letting even less experienced programmers add encryption and authentication services to their apps, features that are becoming indispensable. The library hides low-level details of security from developers. It supports a variety of algorithms for symmetric/asymmetric encryption, authentication, and hashing. The library is free for non-commercial/shareware projects. It is written in C. ActiveX and C++ wrappers are available. Download cryptlib (1.32 Mb) Xceed Encryption LibraryXceed Encryption Library lets Windows apps encrypt/decrypt data using latest industry standard strong encryption algorithms. Supports traditional secret-key encryption & public-key encryption, and can encrypt/decrypt memory buffers, strings, blobs, streaming data or files. Supports AES (US Advanced Encryption Standard) symmetric encryption algorithm (Rijndael) and Twofish, the runner-up for AES. Also offers RSA algorithm with unlimited key sizes.
