When should I use hashing instead of encryption?

When should I use hashing instead of encryption?

Hashing is typically used for data integrity verification, while encryption is for data confidentiality. Can you provide more context?

I want to store user passwords securely. Should I hash them or encrypt them?

You should hash passwords using a strong hashing algorithm like bcrypt. This way, even if the data is compromised, the original passwords cannot be easily retrieved.

What about encrypting sensitive data like credit card information?

For sensitive data like credit card information, encryption is essential. It ensures that only authorized parties can access the data.

Are there any scenarios where I would use both?

Yes, you might hash passwords for storage and encrypt sensitive data for transmission. Each serves a different purpose.
