> Major points in CSR at https://bugs.openjdk.java.net/browse/JDK-8245274:
>
> - new sigalg "RSASSA-PSS", "EdDSA", "Ed25519" and "Ed448" can be used in jarsigner
>
> - The ".RSA" and ".EC" block extension types (PKCS #7 SignedData inside a signed JAR) are reused for new signature
> algorithms
>
> - A new JarSigner property "directsign"
>
> - Updating the jarsigner tool doc
>
> Major code changes:
>
> - Always use the signature algorithm directly as SignerInfo::signatureAlgorithm. We used to use the encryption algorithm
> there like RSA, DSA, and EC. Now it's always SHA1withRSA or RSASSA-PSS.
>
> - Move signature related utilities methods from AlgorithmId.java to SignatureUtil.java
>
> - Add new SignatureUtil methods fromKey() and fromSignature() to simplify creating Signature and getting its AlgorithmId
>
> - Use the new methods in PKCS10, X509CertImpl, and X509CRLImpl signing
>
> - Add a new (and intuitive, IMHO) PKCS7::generateNewSignedData capable of all old and new signature algorithms
>
> - Mark all -altsign related code deprecated and they can be removed once ContentSigner is removed
