FIPS 140-2 requires the use of validated cryptography in the security systems implemented by federal agencies to protect sensitive information. The wolfCrypt Module is a comprehensive suite of FIPS Approved algorithms. All key sizes and modes have been implemented to allow flexibility and efficiency. The National Institute of Standards and Technology (NIST) is sending FIPS […]

Version 1.7.0 of wolfSSL JNI and JSSE is now available for download! wolfSSL JNI and JSSE provides Java applications with a convenient Java API to the widely-used wolfSSL embedded SSL/TLS library, including support for TLS 1.3!  This package provides both a Java JSSE Provider as well as a thin JNI wrapper around native wolfSSL. Release […]

The wolfSSL embedded SSL/TLS library includes three different math libraries which can be used to support wolfCrypt’s cryptographic operations – the Normal Math library, the fastmath library, and SP math.  To help our users decide which math library is right for them, we have put together a helpful comparison matrix! The wolfSSL Math Library Comparison […]

A major release for wolfTPM came out at the end of 2020 and is now available for download from our website. This release brings many new features: Native support for using TPM2.0 hardware with wolfTPM under Microsoft Windows TPM simulator support for even easier development with wolfTPM and MacOS users Protection from MITM (man-in-the-middle) attacks […]

Back in January of 2018 wolfSSL added support for use with the Open Whisper Systems Signal Protocol C Library! This means that you can now develop Signal applications using wolfCrypt as the underlying cryptography provider. For those unfamiliar with the Signal Protocol, it is described on their GitHub page as “A ratcheting forward secrecy protocol […]

The team here at wolfSSL is putting together a Sparkplug example that we’d like to share with you! The Sparkplug specification is useful for Industrial IoT system developers building on top of MQTT. Sparkplug defines a set of device states, adds topic naming structures, and defines payload formats. The wolfMQTT client library is perfectly suited […]

Last year wolfSSL fixed 8 vulnerabilities and documented them in the wolfSSL embedded SSL/TLS library release notes. Thanks to all of the researcher reports, and to the dedicated wolfSSL team, the fixes were identified and resolved rapidly. How rapidly you may ask? The average time to get a fix submitted for review on the vulnerabilities […]

wolfSSL is developing a library to handle the location of where crypto operations run amongst multiple cores. For large systems that have many sign/verify operations happening at once this library would be able to distribute those sign/verify requests based on a user’s input. In addition to managing where the operation runs it can be used […]

The wolfSSL library includes a useful tool for sniffing TLS traffic. This can be used to capture and decrypt live or recorded PCAP traces when at least one of the keys is known. Typically a static RSA ciphersuite would be used, however with TLS v1.3 only Perfect Forward Secrecy (PFS) ciphers are allowed. For TLS […]

The Qualcomm Hexagon SDK  is used for building code to run on DSP processors. Use of the Hexagon toolchain to offload ECC verify operations has been added to wolfSSL. This can free up the main CPU for other operations or lead to future optimizations with HVX on some algorithms that use vector operations. The Makefile […]
