AnonAddy is an open-source anonymous email forwarding service. The name AnonAddy is short for "anonymous email address".
Why should I use AnonAddy?
- Protect your real email address from spam by simply deactivating/deleting aliases that receive unsolicited emails
- Identify who has sold your data by using a different email address for every site
- Protect your identity in the event of a data breach by making it difficult for hackers to cross-reference your accounts
- Prevent inbox snooping by encrypting all inbound emails using GPG/OpenPGP encryption
- Update where emails are forwarded without having to go through and change your email address for each site individually
- Reply to forwarded emails anonymously without revealing your true email address
How does it work?
- Register your username
Let's say your username is johndoe. You can now use *@johndoe.anonaddy.com (or .me) as your email. Where * denotes any valid local part for an email address.
If you would like to remain anonymous choose a username that is not linked to your real name or identify and that you haven't used anywhere else.
- Create Aliases On The Fly (or generate UUID aliases)
Next time you are signing up to a website or newsletter, simply make up a new alias and enter that instead of your real email address.
For example, if you are on vuejs.org and you want to sign up to their newsletter you could simply enter vuejs@johndoe.anonaddy.com (or .me).
We'll automatically create the alias in your dashboard as soon as it receives its first email. You can reply to emails anonymously too!
- Manage Aliases
Let's say a spammer gets hold of one of your aliases and starts sending unsolicited email to it. You can simply toggle a switch in your dashboard and deactivate that alias.
Our system will then silently discard any further emails and you won't be forwarded anything else for that alias.
You can also delete the alias. Then our system will reject any emails and respond with an error.
Bitwarden is the easiest and safest way to store all of your logins and passwords while conveniently keeping them synced between all of your devices.
Password theft is a serious problem. The websites and apps that you use are under attack every day. Security breaches occur and your passwords are stolen. When you reuse the same passwords across apps and websites hackers can easily access your email, bank, and other important accounts.
Security experts recommend that you use a different, randomly generated password for every account that you create. But how do you manage all those passwords? Bitwarden makes it easy for you to create, store, and access your passwords.
Bitwarden stores all of your logins in an encrypted vault that syncs across all of your devices. Since it's fully encrypted before it ever leaves your device, only you have access to your data. Not even the team at Bitwarden can read your data, even if we wanted to. Your data is sealed with AES-256 bit encryption, salted hashing, and PBKDF2 SHA-256.
Bitwarden is 100% open source software. The source code for Bitwarden is hosted on GitHub and everyone is free to review, audit, and contribute to the Bitwarden codebase.
FFmpeg is the leading multimedia framework, able to decode, encode, transcode, mux, demux, stream, filter and play pretty much anything that humans and machines have created. It supports the most obscure ancient formats up to the cutting edge. No matter if they were designed by some standards committee, the community or a corporation. It is also highly portable: FFmpeg compiles, runs, and passes our testing infrastructure FATE across Linux, Mac OS X, Microsoft Windows, the BSDs, Solaris, etc. under a wide variety of build environments, machine architectures, and configurations.
It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications. As well as ffmpeg, ffplay and ffprobe which can be used by end users for transcoding and playing.
The FFmpeg project tries to provide the best technically possible solution for developers of applications and end users alike. To achieve this we combine the best free software options available. We slightly favor our own code to keep the dependencies on other libs low and to maximize code sharing between parts of FFmpeg. Wherever the question of "best" cannot be answered we support both options so the end user can choose.
Everyone is welcome in FFmpeg and all contributions are welcome too. We are happy to receive patches, pull requests, bug reports, donations or any other type of contribution.
Security is a high priority and code review is always done with security in mind. Though due to the very large amounts of code touching untrusted data security issues are unavoidable and thus we provide as quick as possible updates to our last stable releases when new security issues are found.
