The AesKeyGenParams dictionary of the Web Crypto API represents the object that should be passed as the algorithm parameter into 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.


A DOMString. This should be set to AES-CBC,ย  AES-CTR, AES-GCM, or AES-KW, depending on the algorithm you want to use.

A Number โ€” the length in bits of the key to generate. This must be one of: 128, 192, or 256.


See the examples for SubtleCrypto.generateKey().
