Unverified50% confidenceFactExact time
RSA keys commonly used in the 1990s were only 512 bits, partly because U.S. export control regulations had long restricted the export of strong encryption technology.

UnverifiedA security researcher successfully factored the RSA key used by a certificate authority (CA) from the 1990s.64% similarUnverifiedRSA encryption relies on the difficulty of large integer factorization, elliptic curve cryptography relies on the discrete logarithm problem, and cryptographic security is built on the assumption that certain problems are computationally hard to solve.62% similarVerifiedSM2 is based on elliptic-curve cryptography (ECC) with a key length of 256 bits; its security is equivalent to RSA-2048 but with higher computational efficiency, and it is commonly used for digital signatures and key exchange61% similarUnverifiedThe root cause of keychain migration failure is that the encryption key is sealed within the source device's Secure Enclave and cannot be exported, leaving the target device unable to provide the same hardware key for decryption60% similarUnverifiedIn the 1990s, the United States classified strong encryption software as a munitions control item, sparking the famous Crypto Wars.60% similar
