ElcomSoft Co.Ltd. updates Advanced Office Password Breaker, a product to remove password protection from Microsoft Office documents, adding Rainbow Tables for password-protected Excel spreadsheets. Rainbow Tables offer near-instant recovery of 97% of spreadsheets protected with 40-bit encryption used by Microsoft Excel 97-2000 and in documents saved by later versions of the product in compatibility mode.

With the added benefit of Rainbow Tables for quickly recovering the majority of protected Microsoft Excel spreadsheets, the price of Advanced Office Password Breaker does not increase, and remains at $399 US.

The newest release of Advanced Office Password Breaker offers guaranteed near-instant recovery of all Microsoft Word documents and 97% of Microsoft Excel spreadsheets protected with 40-bit encryption. With updated Rainbow Tables, users of Advanced Office Password Breaker will enjoy the ability to unlock most Excel spreadsheets in just minutes instead of days. Rainbow Tables for Microsoft Excel are new to Advanced Office Password Breaker, and come in addition to already available Thunder Tables™ for Microsoft Word. Thunder Tables™ recover password-protected Microsoft Word documents in just seconds, and provide a 100% recovery guarantee of 40-bit encrypted Word files.

"We are one step closer to making 40-bit encryption completely obsolete," says ElcomSoft CEO Vladimir Katalov. "Employing Rainbow Tables to unlock Microsoft Excel spreadsheets advances our products yet another step," he adds. The company is now able to recover all Microsoft Word documents and the majority of Microsoft Excel spreadsheets protected with 40-bit encryption in a few minutes instead of days without performing a brute force attack.

About Rainbow Tables

Advanced Office Password Breaker uses the most advanced cryptographic algorithms to provide as fast recovery of password-protected Office documents as possible. Rainbow Tables are particularly effective in speeding up password recovery, as they use pre-computed hash tables that allow unlocking to 97% of documents protected with 40-bit encryption keys in just minutes instead of days or weeks. Rainbow Tables for Microsoft Excel are shipped on a DVD containing pre-computed hash tables. The same DVD also holds Thunder Tables™ for Microsoft Word that allow recovering all Microsoft Word documents protected with 40-bit keys in only seconds - with a 100% success guarantee.

According to Mr. Katalov, a 100% chance of recovery provided by Thunder Tables™ for Microsoft Word documents is not possible for Microsoft Excel spreadsheets even theoretically due to the differences between the two formats. However, should a particular Excel spreadsheet fall into the 3% category, Advanced Office Password Breaker will still unlock the protected document (typically, in 48 hours or less) with brute force attack on the encryption key.
