With the release of TLS 1.3, there are promises of enhanced security and speed. But how exactly do the changes from TLS 1.2 to TLS 1.3 cause these improvements? The following is a list of differences between TLS 1.2 and 1.3 that shows how the improvements are achieved. wolfSSL is among the first libraries to support […]

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 […]

As stated in the TLS 1.1 and 1.2 protocol definitions (RFC 4346, RFC 5246), “The primary goal of the TLS protocol is to provide privacy and data integrity between two communicating applications.” TLS 1.2 is an improvement to the TLS 1.1 standard, but how exactly do they differ? What was changed in TLS 1.2 to […]

Have you heard talk about SSL 3.0, TLS 1.0, TLS 1.1, TLS 1.2, and TLS 1.3 but never really knew the differences between the different versions? Secure Socket Layer (SSL) and Transport Security Layer (TLS) are both cryptographic protocols which provide secure communication over networks. These different versions are all in widespread use today in […]

As you may have noticed, we released version 3.15.0 of wolfSSL. One of the features in this release was TLS 1.3 Draft 28 support!  Draft 28 is the latest version of the TLS 1.3 specification, and can be enabled in wolfSSL at configure time by using the “–enable-tls13” build option: –enable-tls13 Enable wolfSSL TLS v1.3 (default: […]

wolfSSL is one of over a dozen vendors mentioned in the recent Technical Advisory “ROHNP” by author Ryan Keegan. Versions of wolfSSL prior to 3.15.3 were vulnerable to a Key Extraction Side Channel Attack. wolfSSL v3.15.3 which is protected against these attacks and has other improvements is available for download now on our website. Only […]

wolfSSL will be releasing wolfCrypt v4.0 FIPS with an expanded security boundary. We have added many algorithms to the boundary. We have also tested the code using AES-NI with Linux and Windows 10. Intel added a set of instructions for accelerating AES processing including performing AES-GCM’s GHASH. Also available are accelerations to SHA-1, SHA-2, and […]

wolfSSL will be releasing wolfCrypt v4.0 FIPS with an expanded security boundary. We have added many algorithms to the boundary, including Key Generation. wolfCrypt v4.0 FIPS can generate keys for use with RSA and ECDSA signing. It can also do the perform the ECDHE and DHE key agreement schemes. We have also self-affirmed wolfCrypt for […]

We have been hard at work adding server support for SCP to wolfSSH and it will be available in the next release of wolfSSH, version 1.3.0. If you have an embedded device and want to securely upload a new firmware image to it or download a log file with the convenience of a copy command, […]

wolfSSL is proud to announce release v3.15.0 of our wolfSSL embedded TLS library. Among the many additions are: Support for wolfCrypt FIPS on SGX Support for TLS 1.3 Draft versions Single Precision assembly code added for ARM and 64-bit ARM to enhance performance Improved performance for Single Precision maths on 32-bit Expanded OpenSSL compatibility layer […]
