dumpasn1

Dumps the contents of an ASN.1 encoded file, e.g. an SSL certificate

dumpasn1 is an ASN.1 parser which dumps the contents of an ASN.1-encoded file, as well as interpreting the OIDs contained in the file into human-readable format. Dumpasn1 is intended for examining the contents of PKI certificates and comes with a full list of security-related OIDs, but can be easily extended to parse other OIDs as well.
