ITS#7374 - MozNSS: better file name matching for hashed CA certificate directory
CA certificate files in OpenSSL compatible CACERTDIR were loaded if the
file extension was '.0'. However the file name should be 8 letters long
certificate hash of the certificate subject name, followed by a numeric
suffix which is used to differentiate between two certificates with the
same subject name.
Wit this patch, certificate file names are matched correctly (using
regular expressions).
