ECDSA Benefits

ECDSA (Elliptic Curve Digital Signature Algorithm) provides the same security as RSA with smaller key sizes, making it more efficient for digital signatures.

⚠️

Security Warning

Keep your private key secure and never share it. The public key can be shared freely for signature verification.
