⚡ Endpoint

GET /crypto

POST /crypto

Perform hashing, encryption, or decryption using the specified algorithm.

📥 Query / JSON Body Parameters

Param Type Required Description
text string ✅ Yes Input plain text (for hashing/encryption) or ciphertext (for decryption).
algo string ✅ Yes Algorithm to use. Supported: sha256, sha512, md5, bcrypt, argon2, blake2b, blake2s, aes, rsa, blowfish, chacha20.
action string ❌ No One of: hash (default for hash algos), encrypt, decrypt. Default: encrypt.
key string ⚠️ Depends Required for encryption/decryption (aes, rsa, blowfish, chacha20). Not needed for hash.
iv string ⚠️ Depends Required (Base64) when decrypting AES or Blowfish.
nonce string ⚠️ Depends Required (Base64) when decrypting ChaCha20.

🔑 Supported Algorithms

Hashing

  • sha256
  • sha512
  • md5

🛡️ Security Notes

  • Always keep keys private & secure.
  • bcrypt and argon2 are best for password storage.
  • RSA requires proper PEM-formatted keys.
  • Never log plaintext or keys in production apps.
