get cryptoHashElement(): Element

Implementation of CryptoHashableElement.cryptoHashElement
- Defined in core/elgamal.ts:173
Returns Element

Methods

decrypt

decrypt(secretKey: ElGamalSecretKey | ElGamalKeypair): undefined | number

- Defined in core/elgamal.ts:186
Given knowledge of the secret key, decryption is possible.

Parameters
- secretKey: ElGamalSecretKey | ElGamalKeypair
Returns undefined | number

decryptWithNonce

decryptWithNonce(publicKey: ElGamalPublicKey | ElGamalKeypair, nonce: ElementModQ): undefined | number

- Defined in core/elgamal.ts:193
Given knowledge of only the public key, decryption requires knowing the nonce.

Parameters
- publicKey: ElGamalPublicKey | ElGamalKeypair
- nonce: ElementModQ
Returns undefined | number

equals

equals(other: ElGamalCiphertext): boolean

- Defined in core/elgamal.ts:181
Parameters
- other: ElGamalCiphertext
Returns boolean

isValidResidue

isValidResidue(): boolean

- Defined in core/elgamal.ts:206
Checks whether the components of this ciphertext are valid residues, i.e., whether they are part of the subgroup of P.

Returns boolean

toString

toString(): string

- Defined in core/elgamal.ts:177
Returns string
