DataProtectionDecryptor permits the decryption of Windows passwords and other information that has been encrypted by DPAPI (Data Protection API).

This tool can be easily utilized to decrypt DPAPI data on your current running system, as well as for decrypting DPAPI data stored on an external hard drive. All results can be saved to a file for later use.

DPAPI is a decryption/encryption system used by Microsoft products to decrypt/encrypt passwords and other sensitive information. DPAPI decrypted data will always begin with the following byte sequence, allowing for easy detection: 01 00 00 00 D0 8C 9D DF 01 15 D1 11 8C 7A 00 C0 4F C2 97 EB
