PolarSSL is a light-weight open-source cryptographic library for embedded systems.
Its designed to be:
- Low profile
- Self contained
- Easy to implement
- Very modular
- Easily expandable
It provides standard crypto blocks for: AES, Camellia, SHA-1, SHA-256, SHA512, X.509 certificates, etc. as well as higher lever protocols: SSL v3, TLS v1.0, TLS v1.1 and TLS v1.2.
PolarSSL has been ported on a number of architectures, including ARM, PowerPC, MIPS, and Motorola 68000. Its already small memory footprint can be easily reduced to 50k for a basic SSL client or server, by modifying a single .h configuration file. PolarSSL is currently used in several open-source (GPL) and closed-source projects, such as Adobe's flash player.
