Recently, wolfSSL released version 3.15.5. This new release of wolfSSL features many new updates, one of which is expanded support for PKCS#7 Cryptographic Message Syntax (CMS). This contains support for using PKCS#7 with Key-Encryption Key Recipient Info (KEKRI), Password Recipient Info (PWRI), and Other Recipient Info (ORI) types.
PKCS#7 is used to sign, encrypt, or decrypt messages under Public Key Infrastructure (PKI). It is also used for certificate dissemination, but is most commonly used for single sign-on.
This expanded PKCS#7 support improves how implementations using wolfSSL handle receiving various RecipientInfo types that were not supported, and also allows wolfSSL to more accurately determine the information and details about each recipient.
Additionally, wolfSSL also provides support for TLS 1.3, which includes many new features such as handshake speedups, removal of insecure algorithms, and improved encryption requirements.
