Class: CompactEncrypt

💗 Help the project

Support from the community to continue maintaining and improving this module is welcome. If you find the module useful, please consider supporting the project by becoming a sponsor.

The CompactEncrypt class is used to build and encrypt Compact JWE strings.

This class is exported (as a named export) from the main 'jose' module entry point as well as from its subpath export 'jose/jwe/compact/encrypt'.

Example

const jwe = await new jose.CompactEncrypt(
  new TextEncoder().encode('It’s a dangerous business, Frodo, going out your door.'),
)
  .setProtectedHeader({ alg: 'RSA-OAEP-256', enc: 'A256GCM' })
  .encrypt(publicKey)

console.log(jwe)

setContentEncryptionKey()

▸ setContentEncryptionKey(cek): this

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

Parameters

Parameter	Type	Description
cek	Uint8Array	JWE Content Encryption Key.

Returns

this

Deprecated

You should not use this method. It is only really intended for test and vector validation purposes.

---

setInitializationVector()

▸ setInitializationVector(iv): 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.

Parameters

Parameter	Type	Description
iv	Uint8Array	JWE Initialization Vector.

Returns

this

Deprecated

You should not use this method. It is only really intended for test and vector validation purposes.

setKeyManagementParameters()

▸ setKeyManagementParameters(parameters): this

Sets the JWE Key Management parameters to be used when encrypting. For ECDH based algorithms, use this method to set the "apu" (Agreement PartyUInfo) or "apv" (Agreement PartyVInfo) parameters.

Parameters

Parameter	Type	Description
parameters	JWEKeyManagementHeaderParameters	JWE Key Management parameters.

Returns

this

---

setProtectedHeader()

▸ setProtectedHeader(protectedHeader): this

Sets the JWE Protected Header on the CompactEncrypt object.

Parameters

Parameter	Type	Description
protectedHeader	CompactJWEHeaderParameters	JWE Protected Header object.

Returns

this
