![]() ![]() But any algorithm, any key size, will eventually run out of life. "We came not to bury DES but to praise it," said Bidzos. RSA president Jim Bidzos, a frequent critic of government crypto policy who has been rather quiet lately, defended DES. Triple-DES uses the three separate DES keys, so an attacker would have to break the code three separate times. ![]() Gilmore complained about "mixed signals from the government." Last week, he noted, the National Institute of Standards and Technology urged the use of Triple-DES rather than DES for security while the Commerce Department limits encryption exports to products with 56-bit crypto-the kind just broken in the RSA challenge. RSA sponsors periodic DES-cracking contests to demonstrate that 56-bit encryption, the strongest allowed for export by the U.S. He said the record time to crack DES should send "a wake-up call" to anyone who relies on DES to keep data private. "When designing secure systems and infrastructure for society, listen to cryptographers, not to politicians," said John Gilmore, the EFF co-founder who headed the Deep Crack project.
