Microsoft has announced that it will soon deprecate RSA keys shorter than 2048 bits within Windows Transport Layer Security (TLS).
This decision aims to protect users from potential vulnerabilities and follows industry-wide recommendations for stronger encryption.
RSA (Rivest–Shamir–Adleman) is a commonly used public-key cryptography system for secure data transmission. The security of RSA relies on the difficulty of factoring large numbers. The longer the RSA key, the more difficult it is to break its encryption.
1024-bit RSA keys were considered secure in the past, but advancements in computing power have made them increasingly vulnerable to cracking. Security experts have long recommended using a minimum of 2048-bit RSA keys for robust protection.
