SSL and its SHA-1 algorithm is compromised

SHA-1 is the technical underpinning of Secure Sockets Layer (SSL), a private-key technology used to send secure information over the Internet. In addition, a handful of microchip makers — including Atmel, Infineon, National Semiconductor and STMicroelectronics — use SHA-1 as the basis for their Trusted Platform Modules developed by the Trusted Computing Group to provide a hardware root of trust in PCs and other devices. Hardware tokens are also typically built on the OATH (Open Authentication) standard, a 160-bit protocol that uses SHA-1 at its core.

In February of2005, three Chinese mathematicians announced that they had cracked (reverse engineered) the SHA-1 hashing algorithm. This announcement has caused considerable consternation among security experts owing to the fact that SHA-1 is used in SSL certificates, tokens, trusted platforms, etc. It is now possible to break, on a mathematic level, the security encryption of SSL equipped websites and most hardware-based tokens.

As a result of this failure of SHA-1, the National Institute of Standards and Technology (NIST) has announced plans to abandon SHA-1 and is calling for all regulatory agencies and hardware vendors to migrate to the new SHA-256 hashing algorithm, which is used by PhishCops®, by 2010.

Here is just a sampling of what experts are now now saying regarding the SHA-1 algorithm and SSL.
