My idea for CypherKeep was to be able to take a piece of info, whether it be a text file, audio clip, photo, etc. and be able to encrypt it, timestamp it, archive it, and have it all be verifiable. The idea is:
-encrypt file via nostr keys or password
-hash the file
-optionally publish the hash to OpenTimestamps
-optionally publish the hash to IFPS/Arweave for internet archival
-optionally publish a note to Nostr containing the hash, the OTS proof, the IFPS CID to locate the hash, as well as a note, block-height and UNIX
-download the encrypted data
-download a metadata processing report for each file processed
-be able to decrypt the file via CypherKeep or decrypt locally offline

The website is a massive work-in-progress but would LOVE feedback. Is there an actual use case here? #asknostr
