Android Kerberos with FIPS 140-2 Crypto
Hi! A few years ago we collaborated with the MIT Kerberos team to port Kerberos to Android with wolfCrypt as the crypto engine. We have recently worked to get our wolfCrypt product FIPS 140-2 certified, and as such, can make a FIPS 140-2 version of Kerberos available to the market on Android and other platforms. […]

Curious about how new machine instructions can accelerate crypto algorithms? Most recently we added Intel’s Advanced Vector Extensions (AVX1 and 2) to wolfSSL’s secure hash algorithms. Benchmarks show it improves the performance of SHA-256, 384 and 512 up to 75% (See: figure below). Intel`s AVX1/2 allows 128bit/256bit registers to perform multiple word operations with a […]

A stream cipher encrypts plaintext messages by applying an encryption algorithm with a pseudorandom cipher digit stream (keystream). Each bit of the message is encrypted one by one with the corresponding keystream digit. Stream ciphers are typically used in cases where speed and simplicity are both requirements. If a 128 bit block cipher such as […]
