decrypt from your server

To decrypt the message sent by the server while ensuring its security, please follow the steps outlined below:

Obtain the encrypted message and the encrypted key.

• from post json decryptpass get decryptpass.
• Perform asymmetric decryption using a private key to retrieve the symmetric encryption key and the initialization vector (IV) combined.

Decrypt the original message using the symmetric encryption key and the IV.

• Perform asymmetric decryption using your private key: Decode the received Base64-encoded encrypted key to obtain the ciphertext. Decrypt the ciphertext using your private key to obtain the combined form of the key and IV (i.e., pass+iv).
• Split the key and the IV: From the decrypted pass+iv combination, the first 32 bytes represent the key, and the last 16 bytes represent the IV. Decrypt the message using the symmetric encryption key and the IV:
• Use the split key and IV as parameters to create a decryptor using the same encryption algorithm (aes-256-cbc). Decode the received Hex-encoded encrypted content to obtain the ciphertext. Decrypt the ciphertext using the decryptor to obtain the original message.

Important considerations:

• Ensure that your private key and public key are a matched pair, with the private key used for decryption and the public key used for encryption.
• Ensure that you use the same encryption algorithm (aes-256-cbc) for the decryption operation.
• When splitting the key and IV, the first 32 bytes represent the key, and the last 16 bytes represent the IV.
