I had a little time this weekend and started looking into this again.
I was happy to discover these recent developments:

     *Some new hash and elliptic curve crypto files*
     https://gitlab.com/freepascal.org/fpc/source/-/tree/main/packages/fcl-hash/src

     *Commit which adds support for Java Web Token (JWT) signing*
     https://gitlab.com/freepascal.org/fpc/source/-/commit/47610d5c651a232a2061a44e2358b147ba65ff1c
     (fpjwt.pp has new TJWTKey record, TJWTSigner class, and new
methods TJWT.Sign and TJWT.ValidateJWT)

     *Commit which adds ES256 JWT signing*
     https://gitlab.com/freepascal.org/fpc/source/-/commit/5afaeaa3ac813e5682d0da9de7d17454a4771d2c
     (ES256 signing can be used for Google API service accounts)

Thank you Michael Van Canneyt.  :-)
