Why Encryption Is a Feminist Issue

From domestic violence to activism, encryption protects women and gender minorities from surveillance, control, and harm – but how does it work?

If you are a woman organizing, seeking help, or protecting your autonomy online, encryption may already be safeguarding you. Let’s understand this together?

End-to-End Encryption: We’ll Keep Talking About It Until Everyone Understands

End-to-end encryption protects private communications and the right to privacy – a fundamental right recognised in many legal systems, including Brazil’s. In simple terms, it works like a locked message: only the sender and the intended recipient hold the key to read what is being shared. Even the platform providing the service cannot access the content of these messages.

For women and gender minorities who organise, seek help, or exercise autonomy online, this protection is critical. End-to-end encryption reduces the risks of surveillance, interception, and misuse of personal information, helping to prevent control, harassment, and other forms of harm.

This protection becomes especially important in authoritarian or highly surveilled contexts, where digital communications can be monitored, weaponised, or used as evidence against those who challenge power, report abuse, or engage in activism. In these settings, encryption is often what makes it possible to communicate safely at all.

Understanding how end-to-end encryption works is therefore not just a technical matter — it is essential to protecting privacy, personal safety, and the ability to organise and speak freely online. These protections are not theoretical or distant; they shape people’s lives in very real ways.

For women, LGBTQIA+ people, survivors of abuse, and feminist activists, secure communication is often the difference between safety and exposure, autonomy and control. When encryption is weakened or removed, the highest cost is borne by those who already face increased risks of surveillance, violence, and repression.

Where can we see encryption helping?

Three Ways Encryption Safeguards Rights:

1. Protecting survivors of intimate partner violence: encryption keeps communication with shelters and support groups safe. It shields survivors from stalking, harassment, and abusive partners who try to monitor them. It also enables survivors to document abuse and plan safe exits without fear that their messages will be intercepted by an abuser or a third party.
2. Ensuring safe access to abortion and health services: encrypted messages let women and gender minorities get sensitive health information and abortion care securely, protecting them from legal risks, anti-abortion groups, and surveillance. In countries where abortion is criminalised or heavily restricted, secure communication becomes essential to exercising bodily autonomy without exposure to legal or social harm.
3. Empowering feminist activism and organizing: encryption allows activists to coordinate safely, share information securely, and mobilize around sensitive issues without fear of repression or monitoring. Without strong encryption, movements become more vulnerable to harassment, doxxing, infiltration, and state repression.

When Messages Are Not Protected…

When messages are not protected, a simple conversation can become a risk. What is said in private may be monitored, intercepted, or later used to control, threaten, or silence those who are already most exposed to harm. And those access could happen by governments, companies, abusive partners, or malicious actors, often without the knowledge of those communicating. 

These risks are not shared equally. For women, LGBTQIA+ people, survivors of abuse, and human rights defenders, intercepted communications are often turned into tools of control and intimidation. Messages can be weaponised to threaten, blackmail, stalk, or silence individuals, reinforcing existing power imbalances and patterns of gender-based violence. In these contexts, the absence of encryption does not merely weaken security: it actively deepens vulnerability.

When messages are not protected, power flows to those who can monitor. When they are protected, individuals retain the space to speak, organize, and live with a measure of freedom. The debate over encryption, therefore, is not only about technology – it is about whose security counts, and whose lives are considered acceptable collateral in the pursuit of control.
