The following sections include snippets that demonstrates how you can completeĬommon cryptographic operations in your app. The library specifies a recommended encryption algorithm for you to use. Library to perform these actions in a more secure manner.
Note: When reading and writing local files, your app can use the Security SHA-2 family with ECDSA (eg, SHA256withECDSA) Not require compatibility with a third-party system), we recommend using theĪES in either CBC or GCM mode with 256-bit keys (such as AES/GCM/NoPadding) When you have the freedom to choose which algorithm to use (such as when you do System could cause compatibility problems in future releases. Specifying a provider without using the Android Keystore In other situations, however, Android doesn't guarantee a particular providerįor a given algorithm. If you're using the Android Keystore system, Specify a provider only with the Android Keystore system Note: Except where specified, this advice applies to all Android versions. Security, use the Android Keystore system. This document describes the proper way to use Android's cryptographic facilitiesĪnd includes some examples of its use.
