We are proud to announce that wolfSSL’s static memory feature with FreeRTOS received an update in our latest 3.14.0 release. This feature allows for memory allocation to stack memory instead of using the heap. In previous versions of the wolfSSL embedded TLS library, the library would not compile when trying to use FreeRTOS and static memory. With […]

Read MoreMore TagwolfCrypt v4.0 is on the CMVP Implementation Under-Test List (#TLS13)
We are excited to announce that wolfCrypt v4.0 is currently in process for CMVP validation for FIPS 140-2! We are adding more algorithms to our security boundary including ECDSA, ECDHE, AES-GCM, AES-CCM, SHA-3, and RSA-PSS. Also included is FIPS 186-4 compliant key generation for both RSA and ECC. We will be able to offer TLSv1.3 with […]

Two modes of AES have been added to the embedded TLS library wolfSSL; AES-CFB and AES-XTS. AES CFB (Cipher FeedBack) mode is a stream cipher mode of AES. For the first 16 bytes it encrypts an IV using AES and xor’s the result with the plain text for encryption or the cipher text for decryption. […]

wolfSSL is pleased to announce we are in the process of adding FIPS + SGX to our FIPS certificate! We have updated our SGX-Linux support and are working on adding an example client and server to the existing SGX-Windows project for a complete solution. If you are working with SGX and need FIPS validated crypto […]
