How to define appropriate Crypto-periods for Cryptographic keys

A cryptoperiod is the time span during which a specific cryptographic key is authorized for use. Common government guidelines range from 1 to 3 years for asymmetric cryptography, and 1 day to 7 days for symmetric cipher traffic keys. Factors to consider include the strength of the underlying encryption algorithm, key length, the likelihood of compromise through a security breach and the availability of mechanisms of revoki… WebAug 12, 2024 · Secure Hash Algorithm is a cryptographic hash function designed by the United States’ NSA. SHA-0 (published in 1993) has been compromised many years ago. SHA-1 (1995) produces a 160-bit (20-byte) hash value.
