RsaOaepParams

RsaOaepParams: object

The RsaOaepParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into SubtleCrypto.encrypt, SubtleCrypto.decrypt, SubtleCrypto.wrapKey, or SubtleCrypto.unwrapKey, when using the RSA-OAEP algorithm.

Type declaration

label?

optional label: BufferSource

An ArrayBuffer, a TypedArray, or a DataView — an array of bytes that does not itself need to be encrypted but which should be bound to the ciphertext. A digest of the label is part of the input to the encryption operation. Unless your application calls for a label, you can just omit this argument and it will not affect the security of the encryption operation.

name

name: string

A string. This should be set to RSA-OAEP.
