Encrypt and Decrypt

[stefano75]

Hi all,

I need to encrypt a datasource and then decrypt it for analisys scope.

Using the "Crypto Extension" I correctly see the datasource encrypted but is not useful for me because the MD5 algorithm is not decryptable.

How can do this?

Any suggestions?

Many thanks

I think maybe using the CryptoJS library and then with the "Set Data Value" extension I can set the encrypted value to the datasource selected

Hi @stefano75,

It's called the Crypto extension because MD5 is a cryptographic hash function, but you are correct that it is not encryption. Hashing is one-way only, encryption is two-way.

The problem is, encryption is a very processor-intensive operation, and not best-suited to JavaScript. There are some implementations available, but we do not provide these, because generally they are not required. 

If you really need to use encryption, it would be possible to implement a 3rd party Javascript-based encryption algorithm via an extension in TealiumIQ, but I would strongly advise against this.

I hope this helps. Sorry it's not better news!

Thanks,

Craig.
