BERViewer

New: It's FREE!

BERViewer is a program that allows the user to "view" BER/DER encoded files such as X.509 certificates and S/MIME messages. It comes in a Windows 9x/NT/2K version and a Mac OS X version (will be free soon). It is absolutely FREE! Below is a screen shot, showing two open files:

For more information on ASN.1 see the following links:

• Excellant web site by a good friend Phil Griffin. His Resources page points back to this page.
• If you don't want to register BERViewer, here's a free program by Peter Gutman, under "Security Standards", halfway down the page. The program is called "dumpasn1.c". No, I didn't use it to write BERViewer, but I do use his dumpasn1.cfg for the OIDs. BTW, Peter does have a quote from me concerning PKIX on his page.
• If you want to pay for an ASN.1 compiler, here's the one to get: OSS Nokalva
• Good web site for Object Identifiers (OIDs)
• Another viewer that allows editing Asn1Editor
