Frequently Asked Questions

What is the difference between hashing and encryption?

Hashing is a one-way irreversible cryptographic digest used for checksums and passwords. Encryption is a two-way reversible process that requires a key to decrypt.

Are MD5 and SHA-1 still considered cryptographically secure?

No. MD5 and SHA-1 are vulnerable to hash collision attacks. Modern secure applications should use SHA-256, SHA-512, or adaptive algorithms like bcrypt and Argon2.
