Table of Contents

Overview

The aesDecode function takes encryption_key and encrypted_value as arguments, and returns the decrypted (original) text using AES (Advanced Encryption Standard).

Note: The decryption is performed using 256 bits.

Return Type

  • TEXT

Syntax

<variable> = zoho.encryption.aesDecode(<encryption_key>, <encrypted_value>, <encryption_iv>);

where,

ParameterData typeDescription
<variable>TEXTVariable which will contain the decrypted text value.
<encryption_key>TEXT

The key used during encryption of the text.

<encrypted_value>TEXT

The encrypted text that need to be decrypted.

<encryption_iv>

(optional)

TEXT

An initialization vector that offers stronger security for the encryption.

Note:
  • This parameter should be of 16 characters.
  • The same IV number that is used for encryption should be provided while decrypting the encrypted text.

Examples

info zoho.encryption.aesDecode("passkey", "yf/u6N0HjKWXFFHIEKzG23+CM+BoL4RBPNb4mc0G3hw5q6xPe9KSpUd62Z5sjjSE"); // Returns "This is a secret"

info zoho.encryption.aesDecode("passkey", "5GzwCtoMcLE83Mmt4okldDoddwF7E07kKqSQHLSBPSw=", "0000000000000000"); // Returns "This is a secret"

where:

passkey
This is the encryption key
5GzwCtoMcLE83Mmt4okldDoddwF7E07kKqSQHLSBPSw=
                      (AND)
yf/u6N0HjKWXFFHIEKzG23+CM+BoL4RBPNb4mc0G3hw5q6xPe9KSpUd62Z5sjjSE
These are the encrypted values
0000000000000000
This is the encryption IV
