Class Ecies

extends Object
Elliptic Curve Integrated Encryption Scheme (ECIES).
Uses ECDH for key agreement, HKDF-SHA256 for key derivation, and AES-128-GCM for encryption.

Class summary

AUTHENTICATION-FAILURE -> any
Error thrown when ECIES decryption fails due to a tag mismatch.
encrypt message/Data recipient-public-key/EcKey --curve/string= -> ByteArray
Encrypts the message for the recipient-public-key.

Statics

AUTHENTICATION-FAILURE -> any
Error thrown when ECIES decryption fails due to a tag mismatch.
encrypt message/Data recipient-public-key/EcKey --curve/string=EcKey.CURVE-SECP256R1 -> ByteArray
Encrypts the message for the recipient-public-key.
Returns a ByteArray containing: [2-byte size] [ephemeral-public-key (DER)] [nonce (12 bytes)] [ciphertext] [tag (16 bytes)]
The curve must match the curve of the recipient-public-key.

Methods

operator == other/any -> bool
Whether this object is equal to the other.
By default, identical is used for equality.
Inheritance
Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:

class Pin:
  number/int

  constructor .number:

  operator == other:
    if other is not Pin: return false
    return number == other.number
A class doesn't have to follow the above format, but it must keep the operator in sync with any hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).
stringify -> string
Stringifies this object.
Inheritance
Objects that need a human-friendly string representation should overwrite this method. The default string is based on the internal class-ID.
