Comparison
Which tool should you use?
| Need | Recommended tool | Why |
|---|---|---|
| Create a secret | Password Generator | Generates random values with controlled length and character sets. |
| Calculate modern checksum | SHA256 / SHA512 | SHA is more suitable than MD5 for modern integrity checks. |
| Inspect API session | JWT Decoder | Displays claims such as exp, iat, aud or sub. |
| Share project config | .env Example Generator | Masks secrets while keeping variable names documented. |
Best practices
What to remember before using these tools
- Never paste production secrets into public tools.
- Use SHA-256 or SHA-512 for modern checksums, not MD5 for security.
- Do not confuse JWT decoding with signature verification.
- Document environment variables without committing real values.
- Rotate any token or secret exposed by mistake.

FAQ
Frequently asked questions about security and hash
What is the difference between MD5 and SHA256?
MD5 is a legacy algorithm vulnerable to collisions. SHA256 is more suitable for modern checksums.
Can I store passwords with SHA256 alone?
No. Password storage should use Argon2, bcrypt or scrypt with a salt.
Does decoding a JWT verify its signature?
No. Decoding reads content. Signature verification requires the correct key or secret.
Why generate a .env.example?
It documents required variables without exposing sensitive values.
