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 […]

What is a Stream Cipher?
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 […]

Release 3.4.6 (March 30, 2015) of the wolfSSL lightweight embedded SSL library has bug fixes and new features including: • Intel Assembly Speedups using instructions rdrand, rdseed, aesni, avx1/2, rorx, mulx, adox, adcx . They can be enabled with “–enable-intelasm”. These speedup the use of RNG, SHA2, and public key algorithms. • Ed25519 support at […]
Read MoreMore TagwolfSSL in MySQL
Currently MySQL comes bundled with yaSSL to provide an option for SSL/TLS connections when using a database. An update for MySQL to use the most recent wolfSSL library (formerly CyaSSL) instead of yaSSL is under way. Along with an increased level of security comes the potential to use progressive features offered by wolfSSL – such […]
Read MoreMore TagWhat does the Bar Mitzvah Attack mean for wolfSSL users?
This attack is based on the weak keys that the outdated stream cipher RC4 can sometimes generate. Simply put, stop using RC4 in TLS connections. In fact, wolfSSL (formerly CyaSSL) recently turned off the RC4 algorithm at build time. This will be the default starting with the upcoming 3.4.6 release. There has certainly been a […]
Read MoreMore TagEd25519 Support Coming to wolfCrypt
wolfSSL is adding crypto level use of Ed25519 to wolfCrypt and plans to add TLS use of Ed25519 in the future. Benchmarks of our Ed25519 implementation have shown that the sign time can be reduced by up to 90% and verify time by up to 65% compared with the common ECC-DSA! The following are some […]
