2015-05-13Move Android Keystore impl to android.security.keystore.Alex Klyubin
This moves the non-public API classes backing Android Keystore from android.security to android.security.keystore, a package specially created for Android Keystore. Bug: 18088752 Change-Id: Ibf04d6a26c54d310b0501fc5e34f37b1176324ad
2015-04-24No runtime exceptions during normal use of AndroidKeyStore crypto.Alex Klyubin
This changes the implementation of AndroidKeyStore-backed Cipher and Mac to avoid throwing runtime exceptions during normal use. Runtime exceptions will now be thrown only due to truly exceptional and unrecoverable errors (e.g., keystore unreachable, or crypto primitive not initialized). This also changes the implementation of Cipher to cache any errors encountered in Cipher.update until Cipher.doFinal which then throws them as checked exceptions.

2015-04-13Use JCA names for block modes, paddings, and digests.Alex Klyubin
This replaces int-based enums from KeyStoreKeyConstraints with String values commonly used in JCA API. As part of under the hood refactoring: * KeyStoreKeyCharacteristics and KeyStoreKeyConstraints have been merged into KeyStoreKeyProperties. * KeymasterUtils methods operating on KeymasterArguments and KeymasterCharacteristics have been moved to their respective classes.

2015-04-02Rename KeymasterException to KeyStoreException.Alex Klyubin
The code in question talks to KeyStore which returns error codes which are a mix of keystore and keymaster error codes. To better match the layering of KeyStore on top of keystore and keymaster, this CL renames KeymasterException into KeyStoreException. It also adds human-readable error messages to exceptions raised by keystore rather than keymaster (e.g., key not found). Bug: 18088752 Change-Id: I4cd1235e16518c9f2e8c5557a457774c6e687b88
2015-03-31Hook in user authenticators and their exceptions.Alex Klyubin
Bug: 18088752 Change-Id: I2835dbe51d09587a3081597c6aaf536aa1427e24
2015-03-31Add license banner to recently added AndroidKeyStore files.Alex Klyubin
Bug: 18088752 Change-Id: I027f9530a02cca081aae8eb94833d2fdcb678e9a
2015-03-31Add unauthenticated AES ciphers backed by AndroidKeyStore.Alex Klyubin
This adds the following AES transformations: * AES/ECB/NoPadding * AES/ECB/PKCS7Padding * AES/CBC/NoPadding * AES/CBC/PKCS7Padding * AES/CTR/NoPadding Bug: 18088752 Change-Id: I3e4702e59868f8f2225c31b1c159d20008b9999d
2015-03-30Add HmacSHA256 backed by AndroidKeyStore.Alex Klyubin
This also adds the MAC length constraint on imported HMAC keys. HMAC doesn't work without this constraint at the moment. Bug: 18088752 Change-Id: I8613f58f5d2a84df00bcf6179d13e30619440330
