flattenedDecrypt(jwe, key, options)

▸ flattenedDecrypt(jwe, key, options?): Promise<FlattenedDecryptResult>

Decrypts a Flattened JWE.

This function is exported (as a named export) from the main 'jose' module entry point as well as from its subpath export 'jose/jwe/flattened/decrypt'.

Parameters

Parameter Type Description
jwe FlattenedJWE Flattened JWE.

options? DecryptOptions JWE Decryption options.

Returns

Promise<FlattenedDecryptResult>

Example

const jwe = {
  ciphertext: '9EzjFISUyoG-ifC2mSihfP0DPC80yeyrxhTzKt1C_VJBkxeBG0MI4Te61Pk45RAGubUvBpU9jm4',
