Use of obsolete or weak cryptographic algorithms

9/10 Critical

Developers use outdated or vulnerable encryption algorithms like SHA1 or RIPEMD160, failing to recognize their security limitations. This creates security vulnerabilities that are easily avoidable with modern algorithms.

Query: “What are the most common pain points with SSL/TLS for developers in 2025?”4/9/2026

Until recently, most certificates relied on the SHA1 hashing function, which is now considered insecure. Leaf and intermediate certificates having SHA1 hashing signature are now considered insecure by browser.

Query: “What are the most common pain points with C# for developers in 2025?”4/5/2026

Many developers use obsolete or vulnerable encryption algorithms (which is very easy to avoid). In this case we have for example SHA1 or RIPEMD160, which do not offer a current and very good level of security.
