Hi Everyone,

I have already my data with AES Encryption, I Try decrypt using the function:

**DECRYPT (** [OBJ1] ; [OBJ2] ; AES **)**

Where:

OBJ1: is my encrypted data

OBJ2: is my user-defined key

but, how does it work the functions ENCRYPT() / DECRYPT():

**Algorithm??:**

AES-128

AES-192

AES-256

Mode??:

ECB (Electronic CodeBook)

CBC (Cipher Block Chaining)

CFB (Cipher FeedBack)

OFB (Output FeedBack)

CTR (Counter)

**Padding??**

For example, if I have the string "text1", using **AES-128** with **CBC**:

text to be Encrypted: text1

user-defined key (Length 16): aaaaaaaaaaaaaaaa

AES Encrypted Output: **9LJrNlG2V1EzzJTKMkHLug==**

How could I decrypt this in Longview Analytics?

Thanks!

Tasso Henkesaid 22 months agoHello Cesar,

Longview Analytics uses the AES algorithm with a default key length of 256 bits.

As the encryption is "salted" you can only encrypt and decrypt with the same program, here Longview Analytics. So an encrypted text from another program cannot be decrypted.

Sorry, Tasso
