ECCiphertext class

Provides an authenticated ciphertext with asymmetric ECC encryption/decryption.

This uses ECDH to determine a shared symmetric key between the sender and recipient. The plaintext is encrypted using authenticated AES-GCM. PKCS7 padding is used.

Constructors

ECCiphertext.encrypt({required Uint8List plaintext, required ECPublicKey recipientKey, required ECPrivateKey senderKey})
Encrypts plaintext using the private senderKey and public recipientKey.
ECCiphertext.fromBytes(Uint8List bytes)
ECCiphertext.fromReader(BytesReader reader)
