SimCrypt.NET: AES 256 bit Encryption Tool
SimCrypt.NET is a .NET Framework 1.1 Windows Form application
which provides an easy to use interface for strong portable AES encryption/decryption of any local file,
and automatic download and decryption of URL-based encrypted files. Also supports decryption of
CMS/PKCS #7 EnvelopedData messages.
To Encrypt A Local File:
Select a file to encrypt
Enter a secret password
Encrypt the file
To Decrypt An Encrypted Local File or URL:
Select an encrypted local file or enter a valid and accessible URL in text field
Enter the same password used to encrypt that file
Decrypt the file
Denvelop a CMS/PKCS#7 file
To decrypt CMS/PKCS#7 messages, you must be a "recipient" specified in the EnvelopedData, and your private RSA
key must be available via the current user MY (Personal) certificate store.
[Note: If a valid and accessible url is entered, SimCrypt.NET will automatically download the specified file, save it
to the Desktop location with the same URL filename, and attempt to decrypt. If the url is a path name without an explicit filename appended,
such as http://www.jensign.com, the local saved file is named "_simcrypturl". A WebRequest.Timeout value of 7 seconds is used.
Options:
(1) For decryption, if you wish to have the decrypted file open automatically,
check the "AutoStart" checkbox.
(2) Select B64 checkbox if you want to base64 encode the encrypted file.
