phpseclib: phpseclib3: RSASSA-PSS crl fails validation

Hi. CRLs created with phpseclib3 and signed (RSASSA-PSS) by a RSA-type CA key fails validation with PHP Fatal error: Uncaught phpseclib3\Exception\UnsupportedAlgorithmException: Signature algorithm unsupported in /usr/local/share/phpseclib/File/X509.php:1455 trace: phpseclib3\File\X509->validateSignatureHelper('rsaEncryption', '-----BEGIN PUBL...', 'id-RSASSA-PSS', '\xA7\xB5[\x84=k\xC2\xD6\x14\x0F(\xA1\xD4r\xE4...', '0\x81\x970\v\x06\t*\x86H\x86\xF7\r\x01\x01...')

maybe it makes sense to slightly change the validateSignatureCountable() like https://github.com/kulikov-a/phpseclib/commit/bf4487c504ea5ea2c36ec7cd0e01fed05b41a6fd and separate the steps of key loading and signature parameters loading?

Thanks!!

I’ve made it so that X509 certs with PKCS1 public keys can validate PSS signatures:

Apologies for the delay! I got back from my vacay this past weekend and have since been trying to play catchup at work. I’ll try to look at this this evening - thanks!
