CryptoHelper::verify method seems wrong

[mcorteel-harel]

The CryptoHelper::verify() method (here) uses openssl_pkcs7_verify. But the parameters do not match the documentation at all:

• The first parameter is a MimePart or a content string when it should be a filename
• The third parameter is an output file when it should be null
• The fourth parameter is an array of strings (which actually only contains a single certificate as a string, which comes from PartnerInterface::getCertificate()) when according to this, it should contain an array of filenames.

Am I missing something here?
