RsaOaepParams dictionary of the Web Crypto API represents the object that should be passed as the
algorithm parameter into
SubtleCrypto.unwrapKey(), when using the RSA_OAEP algorithm.
DOMString. This should be set to
BufferSource— 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.
