AES encryption using ABAP FMs or class methods

Former Member — Mon, 12 Oct 2015 10:23:18 GMT

I am trying to encrypt a string data using AES 128 method.

in java, I could use

SampleEncryptDecrypt oSed = new SampleEncryptDecrypt();

//byte[] key = oSed.generateKey(128);

String str1 = "1111111111111111"; //sample key

byte[] key = str1.getBytes();

System.out.println("Key:" + new String(key));

byte[] encryptedData = oSed.encryptData("MyText", key);

System.out.println("encryptedData: " + new String(encryptedData));

String decryptedData = oSed.decryptData(key, encryptedData);

System.out.println("decryptedData:" + decryptedData);

the output is something like:

Key:1111111111111111

encryptedData: ¼+\žÉP³…è®˜JLÏ#Þ

decryptedData: MyText

are there any FMs or class methods in ABAP, that we can use to encrypt using AES 128 algorithm.

I checked in scn, but could not find easy way/sample programs.

thanks

I wrote some code before, hope it helps:

Hello Madhu,

I suggest reading the following documents:

The standard algorithm used by SSF is configured by ssf/ssf_symencr_alg but you also can pass it as parameter to the envelope function module.

Be sure to use a recent SAPCRYPTOLIB patch level, so AES is technically possible.

Regards,

Cris

The SSF libray as documented here is only suited to Document handling and doesnt provide direct aes encryption and descrption.

Still look for call

encrypted_text = Encrypt( algorithm, mode, string, key )

AES-GCM ideally but AES-CBM is better than nothing

does any body know how to call this in ABAP ?
