Methods

encrypt(key: KeyLike | Uint8Array, options?: EncryptOptions): Promise<FlattenedJWE>

Encrypts and resolves the value of the Flattened JWE object.

setAdditionalAuthenticatedData(aad: Uint8Array): this

Sets the Additional Authenticated Data on the FlattenedEncrypt object.

deprecated
setContentEncryptionKey(cek: Uint8Array): this

Sets a content encryption key to use, by default a random suitable one is generated for the JWE enc" (Encryption Algorithm) Header Parameter.

deprecated
setInitializationVector(iv: Uint8Array): this

Sets the JWE Initialization Vector to use for content encryption, by default a random suitable one is generated for the JWE enc" (Encryption Algorithm) Header Parameter.

setKeyManagementParameters(parameters: JWEKeyManagementHeaderParameters): this

Sets the JWE Key Management parameters to be used when encrypting. Use of this is method is really only needed for ECDH based algorithms when utilizing the Agreement PartyUInfo or Agreement PartyVInfo parameters. Other parameters will always be randomly generated when needed and missing.

setProtectedHeader(protectedHeader: JWEHeaderParameters): this

Sets the JWE Protected Header on the FlattenedEncrypt object.

setSharedUnprotectedHeader(sharedUnprotectedHeader: JWEHeaderParameters): this

Sets the JWE Shared Unprotected Header on the FlattenedEncrypt object.

setUnprotectedHeader(unprotectedHeader: JWEHeaderParameters): this
