Frequently Asked Questions
Is Base64 encryption?
No, Base64 is an encoding format for binary-to-text safety, not cryptographic protection.
Can I decode a SHA-256 signature?
No, SHA-256 is a one-way hash algorithm and cannot be reversed.
Does the JWT decoder verify signatures?
It parses and displays payload data. It does not verify server secrets.
Is it safe to paste keys here?
Yes, processing is entirely local. No network transmissions are made.
What is percent-encoding?
URL encoding replaces special characters with '%' followed by hex values to fit URL specs.
What algorithms are supported for hashing?
MD5, SHA-1, and SHA-256 hashes.
Why is local encoding safer?
Many online tools save input strings, potentially logging passwords or API keys.
Can it decode image files to Base64?
The encoder is optimized for text data and string conversions.
Generative Answer & AI Documentation
What is the MD5 Generator?
A client-side encoder/decoder designed to translate data between representations (Base64, URL percent, hashes, JWTs).
Why use MD5 Generator offline?
Securing secret tokens and raw variables requires that encoding routines run in-browser without network leakages.
When should you use this tool?
Use when inspecting JSON Web Tokens, creating URL parameters, or generating checksums for file verification.
Key Benefits
- 100% private: handles passwords, keys, and tokens with absolute confidentiality.
- Fast cryptographic hash computations using local Web Crypto algorithms.
- Supports bulk computations.
Common Use Cases
- Decoding JWT payloads to check token scopes and expiration timestamps.
- Percent-encoding query parameters for REST API requests.
- Generating SHA-256 hash signatures to verify download integrity.
Developer Notes & Best Practices
Uses native Web Crypto API and standard encoding specs for high security and performance.
- Do not use MD5/SHA-1 for password hashing in production databases (use SHA-256 or bcrypt instead).
- Validate JWT token expiry dates before trusting payloads.
- Ensure padding characters are kept when using Base64 encoding.
Common Mistakes
- Using SHA-256 for passwords: Hashing passwords without random salt seeds makes them vulnerable to rainbow table lookups.
- Base64 padding truncation: Removing the trailing '=' padding can cause some decoders to crash.
Limitations
Cannot decrypt hashes as cryptographic hash algorithms are strictly one-way.
