>> Please review these changes to add DES/3DES/MD5 to `jdk.security.legacyAlgorithms` security property, and to add the legacy algorithm constraint checking to `keytool` commands that are associated with secret key entries stored in the keystore. These `keytool` commands are -genseckey, -importpass, -list, and -importkeystore. As a result, `keytool` will be able to generate warnings when it detects that the secret key based algorithms and PBE based Mac and cipher algorithms are weak. Also removes the "This algorithm will be disabled in a future update.” from the existing warnings for the asymmetric keys/certificates.

I think there is still one outstanding comment from Max, but the fix looks good for me now.
