Data encryption

Former Member — Wed, 08 Nov 2006 13:37:43 GMT

hi, i need to encrypt some data in my application.

i have a string and i want to encrypt it with one of the public encryption standards like tdes, aes or anyone other good algorythmus.

i only found functions to calculate a hashcode of a string, but i need to decrypt it later, so i need a symmetric encryption.

anyone a idea if sap provides functions for dataencryption which can be called directly from abap ?

greetings

In how far do you want to encrypt the data? Do you want to store the data in a table in a way, that other people cannot read it?

In case you want to do this, it might be useful to store the data in a table field using the RAW or LRAW format ...

i wanna do several things.

i want to store passwords, and i want store files in encryptet state.

store it in raw or lraw is not acceptable because it would be a easy to convert it back to original state.

ok, the standard users are not able to read this files, but i want to bring acceptable security in my applications.

Then you won´t be able to precede without implementing an own encryption ...

can that really be?

but sap uses ssl encryption for https a.e.

isnt it possible to use the methods behind this?

i guess this runs all over a java interface.

is it possible to run a java-class from within a abap program (or something else in this direction)?

if everything fails i need to implement a own encryption, but dont want to spend so much time for something that should be already implemented
