Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) # java.security Provides the classes and interfaces for the security framework. This includes classes that implement an easily configurable, fine-grained access control security architecture. This package also supports the generation and storage of cryptographic public key pairs, as well as a number of exportable cryptographic operations including those for message digest and signature generation. Finally, this package provides classes that support signed/guarded objects and secure random number generation. Many of the classes provided in this package (the cryptographic and secure random number generator classes in particular) are provider-based. The class itself defines a programming interface to which applications may write. The implementations themselves may then be written by independent third-party vendors and plugged in seamlessly as needed. Therefore application developers may take advantage of any number of provider-based implementations without having to add or rewrite code. ## Package Specification - [**Java™ Cryptography Architecture (JCA) Reference Guide**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/CryptoSpec.html) - PKCS #8: Private-Key Information Syntax Standard, Version 1.2, November 1993 - [**Java™ Cryptography Architecture Standard Algorithm Name Documentation**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/StandardNames.html) ## Related Documentation For further documentation, please see: - [**Java™ SE Platform Security Architecture**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/spec/security-spec.doc.html) - [**How to Implement a Provider in the Java™ Cryptography Architecture**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/crypto/HowToImplAProvider.html) - [**Default Policy Implementation and Policy File Syntax**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/PolicyFiles.html) - [**Permissions in the Java™ SE Development Kit (JDK)**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/permissions.html) - [**Summary of Tools for Java™ Platform Security**](https://docs.oracle.com/javase/8/docs/technotes/guides/security/SecurityToolsSummary.html) - **keytool** ([for Solaris/Linux](https://docs.oracle.com/javase/8/docs/technotes/tools/unix/keytool.html)) ([for Windows](https://docs.oracle.com/javase/8/docs/technotes/tools/windows/keytool.html)) - **jarsigner** ([for Solaris/Linux](https://docs.oracle.com/javase/8/docs/technotes/tools/unix/jarsigner.html)) ([for Windows](https://docs.oracle.com/javase/8/docs/technotes/tools/windows/jarsigner.html)) ## Interfaces |---|---| | [AlgorithmConstraints](https://developer.android.com/reference/java/security/AlgorithmConstraints) | This interface specifies constraints for cryptographic algorithms, keys (key sizes), and other algorithm parameters. | | [Certificate](https://developer.android.com/reference/java/security/Certificate) | *This interface was deprecated in API level 3.
