We need to specify "PBKDF2WithHmacSHA1And8bit" now in order to get precisely the same output as was previously generated with "PBKDF2WithHmacSHA1". We also now try both when it's ambiguous which was used to generate the archive checksums. Bug 12494407 Cherry-pick from master. Change-Id: I2d6081dd62f50f7d493045150b327ed120de7abd

The file "jbmr2-encrypted-settings-abcd.ab" in this directory is an encrypted
|
|
"adb backup" archive of the settings provider package. It was generated on a
|
|
Nexus 4 running Android 4.3 (API 18), and so predates the Android 4.4 changes
|
|
to the PBKDF2 implementation. The archive's encryption password, entered on-screen,
|
|
is "abcd" (with no quotation marks).
|
|
|
|
'adb restore' decrypts and applies the restored archive successfully on a device
|
|
running Android 4.3, but fails to restore correctly on a device running Android 4.4,
|
|
reporting an invalid password in logcat. This is the situation reported in bug
|
|
<https://code.google.com/p/android/issues/detail?id=63880>.
|
|
|
|
The file "kk-fixed-encrypted-settings-abcd.ab" is a similar encrypted "adb backup"
|
|
archive, using the same key, generated on a Nexus 4 running Android 4.4 with a fix
|
|
to this bug in place. This archive should be successfully restorable on any
|
|
version of Android which incorporates the fix.
|
|
|
|
These archives can be used as an ongoing test to verify that historical encrypted
|
|
archives from various points in Android's history can be successfully restored.
