A research paper presented at the Usenix security conference last week detailed a new technique for retrieving encryption keys from electronic devices, a method that is much faster than all previously ...

The cost and time required to break 512-bit RSA encryption keys has plummeted to an all-time low of just $75 and four hours using a recently published recipe that even computing novices can follow.

Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work. My recent story for Quanta explained a newly proved ...

RSA certificates still vulnerable to 2019 flaw, reaearchers say. Update, March 20, 2025: This story, originally published March 17, has been updated with a statement from RSA regarding the encryption ...

A new record has been set for the largest encryption key ever cracked – but your secrets should be safe for now. Long strings of numbers are essential to the encryption that keeps our online data safe ...

Hardware faults are leaking hundreds of supposedly unbreakable encryption keys on to the internet, researchers have found – and spy agencies may be exploiting the loophole to read secret messages. RSA ...

Some of the world’s best known cryptographers – veterans of the crypto wars of the 1990s – say government access to encryption keys is still a bad idea, but is an issue that will never go away because ...

Microsoft has announced that RSA keys shorter than 2048 bits will soon be deprecated in Windows Transport Layer Security (TLS) to provide increased security. Rivest–Shamir–Adleman (RSA) is an ...
