libFuzzer, a fuzzing engine created by LLVM, is now being used to test the wolfSSL library. Below is a short description of libFuzzer, taken from LLVM’s website here. LibFuzzer is linked with the library under test, and feeds fuzzed inputs to the library via a specific fuzzing entrypoint (aka “target function”); the fuzzer then tracks […]

wolfSSL FIPS – A Year in Review (Part 1 of a 3 Part Series)
wolfSSL is pleased to bring our community a report of the past years FIPS activities. In part one of this three-part series we will cover the new Operating Environments (OEs) added to the wolfSSL certificate in the past year + CAVP algorithm testing done by wolfSSL. Part two of this series will cover OEs tested […]
Read MoreMore TagTLS 1.3 Reducing Latency
As we’ve mentioned in a previous blog post one of the key advantages of TLS 1.3 is the reduction in round-trips. Older versions of the TLS protocol require two complete round-trips before the client sends the application data. With TLS v1.3 only 1 round-trip is required! This means network latency has less impact on the […]
Read MoreMore TagwolfCrypt JNI Wrapper and JCE Provider
The wolfCrypt cryptography library is now available to Java developers! wolfSSL recently released a JNI wrapper and JCE provider that wraps the native C wolfCrypt library. The JCE (Java Cryptographic Extension) framework supports the installation of custom Cryptographic Service Providers which can in turn implement a subset of the underlying cryptographic functionality used by the […]
Read MoreMore TagNXP Kinetis K8X LTC support for PKI (RSA/ECC) with #TLS13
As our readers have seen us post about in the past, NXP has a new LP Trusted Crypto (LTC) core which accelerates RSA/ECC PKI in their Kinetis K8x line. The LTC hardware accelerator improves: * RSA performance by 12-17X * ECC performance by 18-23X * Ed/Curve25519 performance by 2-3X. wolfSSL now provides support for TLS […]
Read MoreMore TagwolfSSL has added AFL to its Testing Suite
wolfSSL is glad to announce that it is incorporating American Fuzzy Lop (AFL) into its testing suite.Improving security is the at the heart of what wolfSSL is about. That is why wolfSSL has decided to include the AFL fuzzer to its list of tools. Finding bugs first locally allows our teams to make improvements to […]
Read MoreMore TagUpcoming in wolfSSH v1.2.0
wolfSSH v1.2.0 is currently a work in process. We have just added support for Elliptic Curve algorithms and AES-GCM. The following key exchange and public key algorithms are now available: • ecdh-sha2-nistp256 • ecdh-sha2-nistp384 • ecdh-sha2-nistp521 • ecdsa-sha2-nistp256 • ecdsa-sha2-nistp384 • ecdsa-sha2-nistp521 The new encryption algorithm that is available is “aes128-gcm@openssh.com”, which is an implementation […]
Read MoreMore TagUsing wolfSSL on the Atmel ATECC508A with TLS 1.3 (#TLS13)
As previously announced, the wolfSSL embedded SSL/TLS library and wolfCrypt embedded crypto engine support the Atmel ATECC508A crypto element. This allows wolfSSL to take advantage of the ECC hardware acceleration and protected private key storage on the ATECC508A. Using wolfSSL, ATECC508A users can benefit from both increased ECC performance and secure key storage, thus hardening […]
Read MoreMore TagwolfSSL with Intel SGX and TLS 1.3 (#TLS13)
As we announced last month, wolfSSL now includes a port for Intel® SGX (Software Guard Extensions) with Linux (specifically, Ubuntu 16.04). Using wolfSSL with SGX Linux takes advantage of Intel® SGX technology to separate untrusted and trusted code, isolating the wolfSSL library from potentially malicious applications running on the host machine. Curious about using wolfSSL’s […]
Read MoreMore TagwolfSSL and OSS-Fuzz
Recently, Google announced OSS-Fuzz with the aim of making “common open source software more secure and stable by combining modern fuzzing techniques and scalable distributed execution.” And when they said that they would like to see us at OSS-Fuzz, we were interested. You can read up on OSS-Fuzz at their official Github page, but to summarize the whole thing, […]
