Find weak message digests used inside custom PasswordEncoder implementations

Recipe IDorg.openrewrite.java.security.search.FindWeakDigestInPasswordEncoder
Artifactorg.openrewrite.recipe:rewrite-java-security

Finds calls to MessageDigest.getInstance("...") whose algorithm is unsuitable for password storage, scoped to classes implementing org.springframework.security.crypto.password.PasswordEncoder. Unsalted and non-iterated digests (MD2, MD4, MD5, SHA-1, SHA-224/256/384/512) are unsuitable for password hashing regardless of how they are wrapped. Delegate to BCryptPasswordEncoder, Argon2PasswordEncoder, Pbkdf2PasswordEncoder, or SCryptPasswordEncoder instead of implementing PasswordEncoder yourself.
