org.bouncycastle:bcprov-jdk18on 1.70 -> 1.72 per mvnrepository.com
maven repository does not show that 1.70 is a valid version for this library
https://mvnrepository.com/artifact/org.bouncycastle/bcprov-jdk18on
instead, versions 1.71, 1.71.1, 1.7{2-5} are available. I have chosen the next minor version for a conservative bump and tried all the tests documented in the .gitlab-ci.yml locally.
