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.

name

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

label Optional

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.

See the examples for SubtleCrypto.encrypt() and SubtleCrypto.decrypt().

• SubtleCrypto.encrypt().
• SubtleCrypto.decrypt().
