RSA is aware of the NIST draft that states the intention to deprecate RSA digital signature algorithms of 112 bits (2048-bit keys) by 2030 and to disallow all RSA digital signature algorithms by 2035. There is no impact to RSA products or security stance based on this guidance.

The RSA cryptosystem was initially developed in 1977 by the founders of RSA – Ron Rivest, Adi Shamir and Leonard Adleman. RSA released the public-key RSA cryptosystem into the public domain on September 6, 2000. RSA encryption is still widely used but no longer maintained by RSA. While the algorithm is associated with our founders and the name of our company, it is not a significant part of our products or solutions.

RSA encryption is still commonly used for certificate signing and to establish the TLS 1.2 handshake. RSA continues to review the state of quantum computing and its relation to the RSA encryption algorithms in our products and environments. RSA also continues to follow NIST guidance regarding encryption and quantum computing.
