What is your use for SHA-1? Are you using it in your own code, like `MessageDigest.getInstance("SHA-1")` or do you have signed JARs? Or maybe certificates that use SHA-1? (though I don't think those have been a thing for quite some time)
java.security.MessageDigest for Java 8 supposed to support MD5, SHA-1, and SHA-256 (see https://docs.oracle.com/javase/8/docs/api/java/security/MessageDigest.html). I see references that SHA-1 has been disable for signed JARs (ex., https://bugs-stage.openjdk.java.net/browse/JDK-8270610 and more https://adoptium.net/release_notes.html). However I do not see that SHA-1 has been dropped from MessageDigest. Asking for a friend...
