Using CryptoAPI 2.0 to encrypt/decrypt a file
Posted on 1998-06-17
I am using the CryptoAPI 2.0 to encrypt/decrypt a file in VB 5.0. I have no problems reading the file (using print # and line input # to write/read) one record at a time and encrypting the record and writing it to a file.
The problem is in decrypting the file because when the record is encrypted, it turns ordinary text/numbers into control characters, some of which are carriage returns, end of line, end of file, etc. This causes problems in trying to read that record back and trying to decrypt it.
Does anyone know how to read that encrypted file, record by record so it can be decrypted?
