> Hi!
> {{JwkUtils::fromECPublicKey}} returns key coordinates without leading zeroes because it's using {{BigInteger.toByteArray()}}, which returns only necessary bytes to encode a big integer value, here: [https://github.com/apache/cxf/blob/master/rt/rs/security/jose-parent/jose/src/main/java/org/apache/cxf/rs/security/jose/jwk/JwkUtils.java#L378]
> This causes issues in different libraries, almost everywhere leading zeroes are expected to be present so that coordinate length is not changed depending on data.
