Hardbin is an IPFS based alternative to services like pastebin:
Hardbin is an encrypted pastebin, with the decryption key passed in the URL fragment, and the code and data served securely with IPFS. (IPFS is a distributed content-addressable storage system that is web-compatible; it's basically bittorrent for the web).
If you're viewing this on hardbin.com, then you're using it via the hardbin.com public IPFS gateway. The IPFS gateway you use has the same capabilities as an ordinary web server (i.e. it can modify content at will), so you should make sure to use a gateway you trust. Running a local gateway is the best option. Start with the IPFS Getting Started guide.
Compared to a traditional encrypted pastebin (e.g. ZeroBin), when used over a trusted gateway, neither the code nor the data can be modified as the content hashes are cryptographically verified by IPFS. This means there is no possibility for a server operator to insert malicious code to exfiltrate the plaintext or decryption key. It's the perfect encrypted pastebin.
