Como consecuencia del caso de espionaje masivo de EEUU, las empresas Lavabit y Silent Circle, las cuales ofrecían a sus clientes servicios de correo cifrado (entre otros) han decidido suspender dicho servicio.
El propietario de
Lavabit, Ladar Levison ha publicado esta carta explicando los motivos de la suspensión, así como las acciones judiciales que piensa emprender, y recomendando al mismo tiempo no facilitar los datos privados a empresas con vínculos físicos en EEUU hasta que haya alguna acción del Congreso o decisión judicial al respecto:
http://lavabit.com/My Fellow Users,
I have been forced to make a difficult decision: to become complicit in crimes against the American people or walk away from nearly ten years of hard work by shutting down Lavabit. After significant soul searching, I have decided to suspend operations. I wish that I could legally share with you the events that led to my decision. I cannot. I feel you deserve to know what’s going on--the first amendment is supposed to guarantee me the freedom to speak out in situations like this. Unfortunately, Congress has passed laws that say otherwise. As things currently stand, I cannot share my experiences over the last six weeks, even though I have twice made the appropriate requests.
What’s going to happen now? We’ve already started preparing the paperwork needed to continue to fight for the Constitution in the Fourth Circuit Court of Appeals. A favorable decision would allow me resurrect Lavabit as an American company.
This experience has taught me one very important lesson: without congressional action or a strong judicial precedent, I would _strongly_ recommend against anyone trusting their private data to a company with physical ties to the United States.
Sincerely,
Ladar Levison
Owner and Operator, Lavabit LLC

Por su parte de la empresa
Silent Circle ha emitido el siguiente comunicado, indicando que el servicio Silent Mail es suspendido al no poder garantizarse su privacidad al usar protocolos estándar de internet; el resto de servicios seguros de la compañía (Silent Phone, Text, and Wyes) siguen en marcha ya que ningún dato encriptado de esos servicios pasa por Silent Circle:
https://silentcircle.com/To our Members:
Silent Circle has preemptively discontinued Silent Mail service to prevent spying.
We designed our phone, video, and text services (Silent Phone, Text and Eyes) to be completely end-to-end secure with all cryptography done on the clients and our exposure to your data to be nil. The reasons are obvious -- the less of your information we have, the better it is for you and for us.
Silent Mail has thus always been something of a quandary for us. Email that uses standard Internet protocols cannot have the same security guarantees that real-time communications has. There are far too many leaks of information and metadata intrinsically in the email protocols themselves. Email as we know it with SMTP, POP3, and IMAP cannot be secure.
And yet, many people wanted it. Silent Mail has similar security guarantees to other secure email systems, and with full disclosure, we thought it would be valuable.
However, we have reconsidered this position. We've been thinking about this for some time, whether it was a good idea at all. Yesterday, another secure email provider, Lavabit, shut down their system less they "be complicit in crimes against the American people." We see the writing on the wall, and we have decided that it is best for us to shut down Silent Mail. We have not received subpoenas, warrants, security letters, or anything else by any government, and this is why we are acting now.
We've been debating this for weeks, and had changes planned starting next Monday. We'd considered phasing the service out, continuing service for existing customers, and a variety of other things up until today. It is always better to be safe than sorry, and with your safety we decided that in this case the worst decision is no decision.
Silent Phone and Silent Text, along with their cousin Silent Eyes are end-to-end secure. We don't have the encrypted data and we don't collect metadata about your conversations. They're continuing as they have been. We are still working on innovative ways to improve secure communications. Silent Mail was a good idea at the time, and that time has passed.
We apologize for any inconvenience, and hope you understand that if we dithered, it could be more inconvenient.
