What is Off the Record Messaging (OTR)? How to Send Anonymous Messages using OTR?

In many different scenarios, we want to pass on the information to the right person but don’t want to let the audience know that it is you.

For Example, you want to report a scam in your organization to the Newspapers. But revealing that it is you can ruin your career and may threaten your life. Suppose, there is an article about a company’s scam in the newspaper and the company finds out that you send an encrypted email to someone. Even if they don’t know what information you shared, it is pretty easy for them to guess what was in that email.

Hence, when passing on Sensitive information, it becomes necessary to protect your identity at any cost. Meeting someone in person isn’t the most effective option either. So, what do you do? That’s where OTR comes into play.

What is Off-the-Record Messaging (OTR)?

Off-the-Record Messaging is a method of sending Anonymous messages that also works to keep your identity hidden and secure.

OTR messaging uses various techniques to Hide and keep the information hidden about your identity and the content. A user can install OTR Plugin in only a few supported Instant messaging applications to make them secure.

Off-the-Record Compatible Instant Messengers:

Windows/Linux – Pidgin Instant Messenger, PSI

macOS – Adium, PSI

Android and iOS – Chatsecure, WeeChat

How does Off-the-Record Messaging Work to Secure your Identity and Data?

Secure identity

Off-the-Record Messaging (OTR) uses various techniques to safeguard your identity when you send confidential information and also the data that you send.

OTR uses AES Encryption Standard and Perfect Forward Secrecy (PFS)

To begin with, OTR uses AES Encryption Standard to Encrypt the Data that you send. Hence, the data can only be encrypted when it reaches the ultimate recipient with the help of a decryption key. To further secure the data, OTR also employs the Perfect Forward Secrecy protocol.

Note: Perfect Forward Secrecy protocol creates a new key for every information that is sent. Hence, it is impossible to encrypt all the data with just one key. Hence, in a scenario where the encryption is compromised, it can’t reveal anything sent prior and in the future.

To know more about Perfect Forward Secrecy, read The Perfect Forward Secrecy.

Off-the-Record (OTR) uses Secure Fingerprint for Deniable Authentication

Off-the-Record Messaging is especially secure because it helps secure your identity and allows you to send anonymous messages. A secure Fingerprint isn’t an actual fingerprint but a digital way to identify the person you are talking to or sharing your information with.

In the most extreme cases, where a hacker may compromise the conversation and read the content by decrypting the message. However, he/she wouldn’t even know who were the parties involved in the conversation. This provides a great relief to the people sharing information online and this is how OTR allows you to send anonymous messages.

Off-the-Record (OTR) uses for Deniable Encryption

In Off-the-Record Messaging, it’s impossible to see who holds the key to an encrypted conversation. Also, it is possible to destroy the encryption after it is used, hence, Deniable Encryption.

Once the encryption key is destroyed, an attacker can’t crack down the code and the conversation that two people using OTR had.


Off-the-Record Messaging is a decent way to exchange private messages. Off-the-Record Messaging employs various measures to promote anonymity and privacy.

Though nothing in the world is fully secure and OTR too can be vulnerable sometimes, it is the most secure way to transmit information from a person to another while keeping the identity secure.
