Blockchain Backup Recover your blocked Bitcoin Core wallet fast. Blockchain Backup is a complete web app that handles the complex coordination of concurrent processes and metadata you need to restore access to your wallet. It runs on your own server. The biggest risk to holding your own wallet is losing access to your money. Any damage to your local blockchain can block your wallet for days. Ordinary file backups don't help. Blockchain Backup gets your wallet back fast.
Safelock Mutually exclusive locks are usually the simplest way to get safe concurrent access to a shared resource. But implementing the locks is a bear to get right. Get simple systemwide multithread, multiprocess, and multiprogram safe locks.
Safelog Get instant multithread, multiprocess, and multiprogram safe logs. Safelog also has a much simpler and more powerful api than standard python logging.
Safecopy Safecopy syncronizes drives and directories very carefully. Like rsync, without rsync's insecure default metadata check. Securely copies to and from remote filesystems through sshfs.
Safeget Download verified files, not malware. This is the most effective way to get your users to verify files. With one command Safeget downloads and does the complex security checks that most people skip. Verifies pgp/gpg sigs, hashes, and more. Give them one command that downloads and verifies. They'll verify every time.
