Dimitri Witkowski updated CXF-8402:
-----------------------------------
Description:
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.
