Function for generating OpenSSL-style name hashes
OpenSSL has functions to generate short (eight hex digits) hashes of issuers of certificates and CRLs. These hashes are used by the "c_rehash" script to populate directories of CA certificates and CRLs, e.g. in the Apache web server. Adding this function lets an Erlang program find the right CRL for a given certificate in such a directory.
