Hi All,

I am trying to encrypt and decrypt a field in a table. I am storing the encrypted value as a string in the table. I have written a class with encrypt() and decrypt(). The encrypt works fine but when I try to decrypt i get an error

saying -----------> "Error occurred while encrypting/decrypting."

the code in my decrypt method is below.

public static server EncryptedURLParameter decryptString(str _res)
{
CryptoAPI cryptoAPI;
container decryptedContainer;
ContainerClass concls;

cryptoAPI = new CryptoAPI(99999999999);
decryptedContainer = BinData::stringToData(_res);
decryptedContainer = ContainerClass::blob2Container(cryptoAPI.decrypt(decryptedContainer));

return con2Str(decryptedContainer);
}

Thanks in advance for the help.

I cannot see anywhere 'encrypt' keyword in your code.

Kindly run code as following

public static server EncryptedURLParameter decryptString(str _res) { CryptoAPI cryptoAPI; container decryptedContainer; ContainerClass concls; cryptoAPI = new CryptoAPI(99999999999); decryptedContainer = BinData::stringToData(_res); concls=new ContainerClass([_res]); decryptedContainer=cryptoAPI.encrypt(concls.toBlob());//encrypt decryptedContainer = ContainerClass::blob2Container(cryptoAPI.decrypt(decryptedContainer)); info(con2Str(decryptedContainer));//info for test return con2Str(decryptedContainer); }

I used your code and tested it in job. It returns the same thing as what I have passed.

Not sure what i missed. my class is below. Please correct it

class AVFEncryption

{

container decCon, con, encCon;

}

public static server EncryptedURLParameter encryptString(str _urlParameter)

{

CryptoAPI cryptoAPI;

ContainerClass concls;

container con, encCon;

cryptoAPI = new CryptoAPI(99999999999);

concls = new ContainerClass([_urlParameter]);

encCon = cryptoAPI.encrypt(concls.toBlob());

return BinData::dataToString(encCon);

}

public static server EncryptedURLParameter decryptString(str _res)

{

CryptoAPI cryptoAPI;

container decryptedContainer;

ContainerClass concls;

cryptoAPI = new CryptoAPI(99999999999);

decryptedContainer = BinData::stringToData(_res);

concls=new ContainerClass([_res]);

decryptedContainer=cryptoAPI.encrypt(concls.toBlob());//encrypt

decryptedContainer = ContainerClass::blob2Container(cryptoAPI.decrypt(decryptedContainer));

info(con2Str(decryptedContainer));//info for test

return con2Str(decryptedContainer);

}

Yes, it will return same data what you will pass,, using example I have given above.

The reason is because, I am decrypting same string which I am encrypting.

If you are unable to accomplish this with pure AX code, it is very easy to use the .Net tools available natively in AX for example via the System.Security.Cryptography namespace:

msdn.microsoft.com/.../system.security.cryptography(v=vs.110).aspx

We have implemented something similar for our web users' password authentication with AES encryption and a salted password in AX, so it is definitely doable.

How do you suggest we encrypt our string using

msdn.microsoft.com/.../system.security.cryptography(v=vs.110).aspx

in AX?
