Encryption Analyzer
Identify encryption and encoding methods in seconds. Perfect for security professionals, developers, and researchers analyzing data.

Encrypted/Encoded Data

Only the first 500 characters will be analyzed

Common Encodings/Encryptions:

  • Base64 (e.g., SGVsbG8=)
  • Hexadecimal (e.g., 48656c6c6f)
  • MD5 (e.g., 5d41402abc4b2a76b9719d911017c592)
  • SHA-1 (e.g., aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d)
  • SHA-256 (64 hex chars)
  • ROT13, Caesar cipher

About this tool

Frequently asked questions

What is the difference between encoding, hashing and encryption?

Encoding, like Base64 or hex, only changes how data is written, and anyone can reverse it. Hashing, like MD5 or SHA-256, turns data into a fixed-length fingerprint that cannot be reversed. Encryption scrambles data with a key, so only someone with the key can read it.

How can I tell an MD5 hash from SHA-256?

Length is the quickest clue. In hex, MD5 is 32 characters, SHA-1 is 40, SHA-256 is 64 and SHA-512 is 128, while Base64 strings mix letters, digits, + and / and often end in = padding. The AI looks at clues like these when it suggests a method.

Can it decrypt or crack my data?

No. It is built to identify the likely method and explain why, not to decrypt or crack anything. Hashes cannot be reversed and real encryption needs the key, so treat the answer as an educated guess, since short strings can match several formats.

Is my data sent to a server?

Yes. What you paste is sent to OpenTools' servers, and the first 500 characters go to an AI model for analysis. Do not paste live passwords, private keys or session tokens; use a sample in the same format instead.
