Android Generate Aes Gcm Key
Definition
Keymaster Functions. Only Tag::KEYSIZE is necessary to generate an AES key. If omitted, the method returns ErrorCode::UNSUPPORTEDKEYSIZE. Supported values are 128 and 256, with optional support for 192-bit AES keys. AES GCM mode supports 'associated authentication data,' provided via the Tag::ASSOCIATEDDATA tag in the. For AES-CTR, AES-CBC, AES-GCM, or AES-KW: pass an AesKeyGenParams object. Extractable is a Boolean indicating whether it will be possible to export the key using SubtleCrypto.exportKey or SubtleCrypto.wrapKey.
