I registered But still no confirmation email.

The email address confirmation email may have been placed in your junk email folder or filtered with a spam filter, so check these first.

If the email isn't received, click on the Register button in the app, enter your email address and click the 'Resend Confirm Email' button to have another confirmation email sent to your email address.


How to Use In a nutshell.

Create a group, invite others by email address, accept or decline the invite, publish to a group, download from a group.


How do I change My Password?

After signing into the blindrelay app, there is a Change Password feature on the main screen.

You will need your current password to complete the process.

Backups of your encryption keys are made whenever you change your password (unless you choose not to create key backups. blindrelay believes you should allow the system to create key backups, but you might have your own reasons not to.).


What if I forget My Password?

Well... since your password is a vital part of the encryption key wrapping process, this could be a problem.

However, the blindrelay app does have a way to roll back to a previously used password. (If you can remember that.) The downside being that if you joined any groups between password changes, you may lose access to those groups and downloaded files if the files are encrypted.

Your password is key (no pun) to nearly everything the blindrelay app does, so it's best not to forget your password.


Can I first encrypt with File Protector And then publish?

Yes, of course, since the encrypted output files (.brx) are just files.

Doing so could add yet another layer of protection. You can encrypt the .brx files themselves multiple times, with different passwords each time, and then decrypt with passwords in reverse order. It's a fun exercise.

If you forget the password you used for File Protector encryption, you are out of luck decrypting the file until you do remember the password.

To use File Protector, simply enter the encrypt/decrypt password. If you want to encrypt files, click on Encrypt Files. To decrypt, click on Decrypt Files. Select one or more files to encrypt or decrypt. It's that easy.

Files are encrypted to blindrelay's .brx file format 'In-Place'. Backups are not made during the encrypt/decrypt process.


Password Manager Throw away that sticky note.

Once you buy the Password Manager in-app subscription, managing passwords becomes much easier than trying to find that sticky note.

Passwords and secrets are 256bit AES encrypted with your password on your device, transmitted over HTTPS, and stored in the ether, where the encrypted data is yet again encrypted at rest.


Can I preview downloads Without officially decrypting them?

Yes, in the Encrypted Download Manager Download Manager, you may click on the filename of PDF, some media files, and text files, and a preview window will appear. (Not all formats are supported.)

To decrypt the files to an output folder of your choosing, check the boxes beside the files you want to decrypt and click on the unlock icon Decrypt Icon. To delete encrypted files, check the boxes by the files you want to delete and click on the trash can Delete File to permanently delete.

To enable previewing large files, a decrypted file is created in the app's temporary folder. A best effort is made to delete decrypted files in the temporary folder after previewing, during app startup and app shutdown. blindrelay cannot guarentee that the temporary decrypted file will always be deleted after previewing for various technical reasons.


Why are encrypted files Sometimes smaller than the original?

In order to save bandwidth and server storage space, files are first compressed and then encrypted before publishing. This may result in an encrypted file that is smaller than the original. Decryption happens in reverse: first files are decrypted and then decompressed.


How do I know my files weren't tampered with?

blindrelay uses a couple of different methods to help determine that files probably weren't tampered with after being encrypted.

For published files, during the encryption process, after compression and encryption are complete, an HMACSHA256 signature is generated and embedded in the encrypted file payload.

For downloaded files, during the decryption process, before decryption and decompression are complete, the embedded HMACSHA256 signature is compared against a new HMACSHA256 signature of the payload, and if the signatures do not match, decryption stops and a warning issued.

File Protector adds a couple of additional steps.

Before encryption, blindrelay does a quick MD5 hash over the original file to generate an MD5 signature.

After the embedded HMACSHA256 signature has been verified and decryption completed, an MD5 signature is created over the decrypted file and compared against the MD5 signature originally created. Both MD5 signatures must match.


I want to use blindrelay For illegal activity. May I?

NO! YOU MAY NOT!!!
