This is a commandline tool to restore encrypted key backups with the same tools the Android wallet would. For example with the encrypted private key
xEncGXICZE1_eVYfGWDioNu_8hA6RZzep4XqwPGRtcKb01MDg3s1XFntJYI9Dw
and its password
QDTDXOYFBXBKKMKR
running
./gradlew :backuputil:run --args "xEncGXICZE1_eVYfGWDioNu_8hA6RZzep4XqwPGRtcKb01MDg3s1XFntJYI9Dw QDTDXOYFBXBKKMKR"
