Something like X509Certificate.toString would be very unfriendly if it returned a one-line String, or if the toString impls of different fields used different formatting.

New commit and the output will look like:
PSSParameterSpec[hashAlgorithm=SHA-256, maskGenAlgorithm=MGF1ParameterSpec[hashAlgorithm=SHA-256], saltLength=32, trailerField=1]
I'm using the ASN.1 field names here. (Precisely the name in MGF1 is OAEP-PSSDigestAlgorithms but that's too long).
