Class IbeCiphertext

IBE (Identity Based Encryption)

Index

Methods

decrypt serialize deserialize encrypt

Methods

decrypt

decrypt(vetkd: VetKey): Uint8Array
Decrypt an IBE ciphertext, returning the message
Parameters
- vetkd: VetKey
Returns Uint8Array
- Defined in utils/utils.ts:902

serialize

serialize(): Uint8Array
Serialize the IBE ciphertext to a bytestring

Returns Uint8Array
- Defined in utils/utils.ts:832

`Static`deserialize

deserialize(bytes: Uint8Array): IbeCiphertext
Deserialize an IBE ciphertext
Parameters
- bytes: Uint8Array
Returns IbeCiphertext
- Defined in utils/utils.ts:845

`Static`encrypt

encrypt(
    dpk: DerivedPublicKey,
    identity: IbeIdentity,
    msg: Uint8Array,
    seed: IbeSeed,
): IbeCiphertext
Encrypt a message using IBE, returning the ciphertext

The seed parameter must be a randomly generated value of exactly 32 bytes, that was generated just for this one message. Using it for a second message, or for any other purposes, compromises the security of the IBE scheme.

Any user who is able to retrieve the VetKey for the specified derived public key and identity will be able to decrypt this message.
Parameters
- dpk: DerivedPublicKey
- identity: IbeIdentity
- msg: Uint8Array
- seed: IbeSeed
Returns IbeCiphertext
- Defined in utils/utils.ts:878
