A block cipher is an encryption method that applies a deterministic algorithm along with a symmetric key to encrypt a block of text, rather than encrypting one bit at a time as in stream ciphers. For example, a common block cipher, AES, encrypts 128 bit blocks with a key of predetermined length: 128, 192, or […]

wolfCrypt FIPS 140-2 Algorithm Certificates
wolfSSL is proud to announce that several wolfCrypt algorithms have received FIPS 140-2 algorithm certificates. The National Institute of Standards and Technology (NIST) website has been updated to reflect wolfSSL`s validation. wolfSSL`s wolfCrypt has received the following certificate numbers and can be viewed at the respective links. AES validation certification #3157 https://csrc.nist.gov/projects/cryptographic-algorithm-validation-program/details?validation=3157 Triple DES validation certification #1800 […]

Read MoreMore TagwolfSSL Assembly Optimizations for ARM Processors
If you are looking for an SSL/TLS library to provide security in connected ARM environments, wolfSSL is by far the best choice. wolfSSL is an ARM partner, and our code has been optimized for ARM environments. Public key operations in CyaSSL (wolfSSL) have optimized assembly code that gives wolfSSL faster RSA, Diffie-Hellman, and DSA times. […]
Read MoreMore TagwolfSSL and CyaSSL Users SAFE from POODLE bites again attacks
Some TLS implementations are vulnerable to the October POODLE attack that at the time was thought to be limited to SSLv3 only: https://www.imperialviolet.org/2014/12/08/poodleagain.html . These implementations are incorrectly using a SSLV3 decoding function while in TLS mode. wolfSSL is not susceptible, it correctly uses TLS decoding while in TLS mode. We would like to reiterate Adam Langley’s […]
Read MoreMore TagWe are happy to announce the release of wolfSSL version 3.3.0
CyaSSL version 3.3.0 offers: • Secure countermeasures for Handshake message duplicates, CHANGE CIPHER without FINISHED, and fast forward attempts added to our source code. Thanks to Karthikeyan Bhargavan from the Prosecco team at INRIA Paris-Rocquencourt for the report. This is an important fix and all users should update! • Complete testing for FIPS 140-2 version […]
