wolfSSL’s wolfcrypt library includes several cryptographic algorithms that are now considered broken or deprecated. While these algorithms are typically disabled by default, developers should be aware of their security implications. Here is the list of these algorithms along with links to documents explaining why they are no longer considered secure: RC4/ARC4: Prohibited for TLS use […]
