Apple and Google sign letter urging Obama to support encryption

Cryptologists join call for US president to resist pressure from FBI and surveillance agencies to build back doors in operating systems

Apple, Google, other tech giants and a number of noted cryptologists have signed a letter to the Obama administration urging the US government to preserve strong encryption against pressure from law enforcement and surveillance agencies.

The letter argues that "strong encryption is the cornerstone of the modern information economy's security," and that the government should "fully support and not undermine efforts to create encryption standards [nor] in any way subvert, undermine, weaken or make vulnerable" commercial software.
