ECC Cryptography Server

ECC Cryptography Tool

A user-friendly tool for Elliptic Curve Cryptography. Generate keys, encrypt messages, and decrypt them using ECC - a public-key cryptosystem that provides strong security with smaller key sizes compared to RSA.

Key Generation

Select Elliptic Curve: secp256r1 (P-256) - Recommended secp384r1 (P-384) - Higher Security secp521r1 (P-521) - Maximum Security

About ECC Keys

ECC uses the mathematics of elliptic curves to provide strong security with much smaller keys compared to RSA. A 256-bit ECC key provides similar security to a 3072-bit RSA key.

Important: Keep your private key secret! The public key can be shared with anyone to encrypt messages that only you can decrypt.

Encryption

Message to Encrypt: Hello, this is a secret message!

Recipient's Public Key:

Encrypted Message (Ciphertext):

No encrypted message yet. Generate keys and encrypt a message.

Decryption

Ciphertext to Decrypt:

Your Private Key:

Decrypted Message:

No decrypted message yet. Provide a ciphertext and your private key.

How to Use This Tool

1. Generate ECC keys (public and private)

2. Share your public key with others so they can encrypt messages for you

3. Use someone else's public key to encrypt messages for them

4. Use your private key to decrypt messages encrypted with your public key
