{{ APIRef("Web Crypto API") }}
The AesKeyGenParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into {{domxref("SubtleCrypto.generateKey()")}}, when generating an AES key: that is, when the algorithm is identified as any of AES-CBC, AES-CTR, AES-GCM, or AES-KW.
name
AES-CBC, AES-CTR, AES-GCM, or AES-KW, depending on the algorithm you want to use.length
Number — the length in bits of the key to generate. This must be one of: 128, 192, or 256.See the examples for {{domxref("SubtleCrypto.generateKey()")}}.
{{Specifications}}
Browsers that support any of the AES-based algorithms for the {{domxref("SubtleCrypto.generateKey()")}} method will support this type.
