Nearly 200 Internet and digital rights experts, companies and organizations are collectively calling on the Obama administration and other world leaders to oppose any efforts to create "back doors" to encryption.
"We urge you to protect the security of your citizens, your economy, and your government by supporting the development and use of secure communications tools and technologies, rejecting policies that would prevent or undermine the use of strong encryption, and urging other leaders to do the same," they said in an open letter made public on Monday.
"Encryption tools, technologies, and services are essential to protect against harm and to shield our digital infrastructure and personal communications from unauthorized access."

Special Rapporteur for Freedom of Opinion and Expression; Iceland parliament member Birgitta Jónsdóttir; the American Civil Liberties Union; Amnesty International; and Human Rights Watch.
