Unknown Verisign VPN extension: CertEnumCertificatesInStore and friends provide a malformed certifcate. When security systems treat risk as a purely boolean process, they're prone to failure because the quantisation that's required in order to produce a boolean result has to over- or under-estimate the actual risk.

Topics covered include measures to prevent automated address harvesting and use, spam-prevention techniques and problems therein, credit card fraud and online banking security issues like phishing attacks, and the use of opportunistic encryption mechanisms to provide a measure of easy-to-use and easy-to-manage security for people who wouldn't otherwise employ it.

Conversely, some problems can be dumpasb1 using far simpler mechanisms than the ones that cryptographers come up with, often by moving the goalposts slightly to make the problem solvable, if less cryptographically interesting. Topics covered include measures to prevent automated address harvesting and use, spam-prevention techniques and problems therein, credit card fraud and online banking security issues like phishing attacks, and the use of opportunistic encryption mechanisms to provide a measure of easy-to-use and easy-to-manage security for people who wouldn't otherwise employ it.

For example, here's Gutmann's dumpasn1 on the Microsoft Root Certificate: Although the basic building blocks for working with strong windiws have become fairly widespread, experience has shown that implementers frequently misuse them in a manner which voids their security properties.

This means that it's no longer necessary to ask a CA for permission to encrypt data, keys can be rolled over regularly at no cost, and if a key is compromised it can be quickly replaced. Download ppt "Digital Certificates Principles of operation".

I also yanked out the error checking to keep the size down. The paper An Open-source Cryptographic Coprocessorpresented at the Usenix Security Symposiumpresents a general-purpose open-source crypto coprocessor capable of securely performing crypto operations such as key management, certificate creation and handling, and email encryption, decryption, and signing, at a cost one windoes two orders of magnitude below that of commercial equivalents while providing generally equivalent performance and a higher level of functionality.

If you need to know what you're in for when you work with PKI, this is definitely the one to read. It doesn't have to be that bad though.
