Processing Time:

WordDecryptor allows you to reset your documents passwords, but doesn't recover them. Protected *.doc and *.dot files are encrypted with short fixed length encryption keys which are recoverable. These keys allow our tool to decrypt protected documents.
The following tables shows maximum processing time based on several tests with the common laptop and workstation CPUs as well as mid-range GPUs:

CPU ¹:
Time:

Intel Core2 Duo T7500 @ 2.20GHz	Intel Core i3 2100 @ 3.10GHz	Intel Core i7 2600 @ 3.40GHz
up to 3 days	up to 1.5 days	up to 18 hours

CPU ¹+ GPU ²
Time:

Intel i3 2100 @ 3.10GHz + AMD Radeon HD 6770	Intel i3 2100 @ 3.10GHz + NVIDIA GeForce GTX 470	Intel Core i3 4130 @ 3.40GHz + AMD Radeon R9 270
up to 16 hours	up to 10 hours	up to 8 hours

¹ The time shown is equal to maximum time necessary to check all "encryption keys" and the key search for most files require just a portion of this time.
² GPU performance is somewhat variable with number of factors including GPU/CPU combination and even driver version. Please contact us if your processing time is noticeable different from data above.
