Decrypting Base64 Encrypted Data in SQL Server

Hello everyone,

In this article, I will try to give information about decoding Base64 encrypted data in SQL Server.

In SQL Server, in some cases, you may want to decrypt Base64 encrypted data.

You can easily do this using the code below.

        CAST('' AS XML).value('xs:base64Binary(sql:column("BASE64_COLUMN"))', 'VARBINARY(MAX)')
    ) AS Sonuc
        SELECT 'WWF2dXogU2VsaW0gS2FydA==' AS BASE64_COLUMN
    ) A

When you create and run the above code, you will see a result similar to the one below.
