Microsoft Announces Deprecation of 1024-Bit RSA Keys in Windows
20 March 2024
1024-bit RSA keys have approximately 80 bits of strength, while the 2048-bit key has approximately 112 bits, making the latter four billion times longer to factor. Experts in the field consider 2048-bit keys safe until at least 2030.
