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
kulikov-a@bf4487c
and separate the steps of key loading and signature parameters loading?

Thanks!!
