Many banks — HDFC, SBI, ICICI and most Indian banks especially — email statements as password-protected PDFs. These convert normally; they just need the password once.
How to convert one
Drop the file as usual. The converter detects the protection and shows a password field — enter the document password and the statement decrypts and converts in one step. The password is used only to open the file and is never stored.
Finding the password
The email your statement arrived with almost always states the format. Common patterns: your date of birth as DDMMYYYY (HDFC, SBI and others), your customer ID, or a combination of name letters and birth year. It's the same password you'd use to open the PDF in any reader.
"That password didn't work"
The check is exact — capitals, order, no spaces. Open the PDF in your normal PDF viewer with the same password first; if it doesn't open there either, the password is wrong. If it opens there but not here, contact support@norekey.com — some exotic encryption variants are worth our attention.
In a batch
Batch mode can't pause for passwords: a protected file in a multi-file batch is flagged with "convert it on its own", while the rest of the batch carries on. Drop the protected file onto the converter by itself and the password field appears.
