Shared pocket book markdown
Read full descriptionHide full description
Overview It is a memo application that supports encryption. Various passwords and confidential information can be safely shared by individuals and limited groups. HTML and markdown previews are available. Notes can be shared with multiple people. It is possible to encrypt a specific memo. Cryptography can also be managed by biometric authentication. If you accidentally delete it, you can go back in time and easily restore what others have accidentally changed. Sharing method I'm using git for sharing. Please set the URL of git to the URL. You can use git service such as github and bitbuscket. Since I want to give priority to simple operations, I basically omit branch operations, tags, and stash functions. Cryptography I'm using the tombo project. You can share it with other by Git. tombo project https://ja.osdn.net/projects/tombo/ -------------------------------------------------- -------------------------------------------------- --------------------------------------------- Twitter:@sharedkeymemo E-Mail:shrinkmanpic@gmail.com
