What are the differences between SHA-256 and MD5?
SHA-256 is part of the SHA-2 family and is more secure than MD5, which is considered weak and vulnerable to attacks.
Why is MD5 considered weak?
MD5 is susceptible to collision attacks, where two different inputs produce the same hash, making it insecure for cryptographic purposes.
When should I use SHA-256 instead of MD5?
You should use SHA-256 for any security-sensitive applications, such as digital signatures or certificate generation, due to its stronger security.
Are there any performance differences between the two?
Yes, MD5 is faster than SHA-256, but the speed comes at the cost of security. For most applications, the security of SHA-256 outweighs the performance.
