ViewBer is a free utility that displays the ASN.1 structure of a BER-encoded file. ViewBer can be used to view the contents of DER and PEM encoded X.509 certificates, PKCS#12, PKCS#10, CSR files, PKCS#7, etc.
ViewBer supports the recursive decoding of OCTET STRING and BIT STRING objects, and includes a catalog of many commonly used OIDs in ASN.1 structures.
