Visual Basic for Applications (VBA)

Top  Previous  Next

 

Microsoft® Visual Basic for Appications (VBA) allows to use a Password to protect Macros from reading their source code. When this Password is set a Password Record is appended to the VBA Macro Storage. Nothing is encrypted. In VBA version 5 the Password is stored encrypted by "XOR" logical operation. In VBA version 6 SHA-1 Password Hash is stored and Password cannot be recovered instantly. But we don't need to recover a Password to view the Macro source codes. We can modify or remove the Password Record.

 

AOPR shows the VBA Password if VBA version is 5 and allows to change or delete the Password if version is 6.

 

Professional Edition of AOPR has a "VBA Backdoor" Feature that allows to bypass VBA Password checking in any Application.
