PGP Encryption and Decryption in C#

-

Add package called PgpCore from NuGet Package manager.

Code example:

    

using (PGP pgp = new PGP())
{
    // Generate keys
    pgp.GenerateKey(@"C:\TEMP\keys\public.asc", @"C:\TEMP\keys\private.asc", "email@email.com", "password");
    // Encrypt file
    pgp.EncryptFile(@"C:\TEMP\keys\content.txt", @"C:\TEMP\keys\content__encrypted.pgp", @"C:\TEMP\keys\public.asc", true, true);
    // Encrypt and sign file
    pgp.EncryptFileAndSign(@"C:\TEMP\keys\content.txt", @"C:\TEMP\keys\content__encrypted_signed.pgp", @"C:\TEMP\keys\public.asc", @"C:\TEMP\keys\private.asc", "password", true, true);
    // Decrypt file
    pgp.DecryptFile(@"C:\TEMP\keys\content__encrypted.pgp", @"C:\TEMP\keys\content__decrypted.txt", @"C:\TEMP\keys\private.asc", "password");
    // Decrypt signed file
    pgp.DecryptFile(@"C:\TEMP\keys\content__encrypted_signed.pgp", @"C:\TEMP\keys\content__decrypted_signed.txt", @"C:\TEMP\keys\private.asc", "password");

    // Encrypt stream
    using (FileStream inputFileStream = new FileStream(@"C:\TEMP\keys\content.txt", FileMode.Open))
    using (Stream outputFileStream = File.Create(@"C:\TEMP\keys\content__encrypted2.pgp"))
    using (Stream publicKeyStream = new FileStream(@"C:\TEMP\keys\public.asc", FileMode.Open))
        pgp.EncryptStream(inputFileStream, outputFileStream, publicKeyStream, true, true);

    // Decrypt stream
    using (FileStream inputFileStream = new FileStream(@"C:\TEMP\keys\content__encrypted2.pgp", FileMode.Open))
    using (Stream outputFileStream = File.Create(@"C:\TEMP\keys\content__decrypted2.txt"))
    using (Stream privateKeyStream = new FileStream(@"C:\TEMP\keys\private.asc", FileMode.Open))
        pgp.DecryptStream(inputFileStream, outputFileStream, privateKeyStream, "password");
}

This post provides tips about different find function in Business Central, including both long-standing C/AL strategies and newer concepts like partial records. FindSet vs FindFirst/FindLast FindSet and FindFirst/FindLast are two methods utilized in Dynamics 365 Business Central for extracting records from a table. The key distinction between them is that FindSet fetches a group of records, whereas FindFirst only fetches the initial record in the filter and FindLast fetches the last record. FindSet is employed when there’s a need to traverse through a sequence of records, and it’s advisable to use FindSet(true) if there’s a requirement to alter any record within the group. Conversely, FindFirst/FindLast is employed when only the initial or last record is needed and there’s no requirement for a loop. SetLoadFields  The SetLoadFields function only loads the specified fields, thereby not fetching the remaining fields in the table and ensuring a quicker load. It is suitable for searchi...
