So, if you want to store secret records that can be read again, hashing is not the solution. This makes it specific to cases like authentication, not general encryption.
Head-to-head Comparison: AES vs Hashing
Now, let’s compare the two directly. AES is a two-way method—data can be encrypted and decrypted. Hashing is one-way—data can only be hashed, not back. AES requires a key to be protected, while hashing doesn’t require a key at all.
In terms of speed, AES is superior for large data, but hashing is more phone number list practical for quick verification. For passwords , hashing is usually preferred because of its irreversibility. But if you want to protect important files, AES is the answer.
When to Use AES Encryption?
AES is a good choice if you want to protect data that needs to be accessible again. For example, when sending confidential messages via email or storing documents in the cloud. AES is also suitable for applications that require high levels of security, such as VPNs or banking systems.
But remember, if you use AES, make sure the key is stored in a super safe place—don’t let it become your own security hole. AES is a great tool, but it has to be used wisely.
