plain text can be enctypted like password in vi editor?

Question

Can anyone tell me, How to plain text can be enctypted like password (********) in vi editor or using vi editor or any other method ?

Answer 1

It's not entirely clear to me what you really want to achieve

• If you want to encrypt the whole file with vim, you can simply run vim -x myfile.txt and vim will ask you for a passphrase to encrypt your file. On next opening of the file, you don't even need to use -x as vim will find out that it is encrypted and will ask you for the passphrase.

• If you want to encrypt only a string in a file with vim, you can run an external command, or you use this help from the Vim Wikia.

• If you want to replace all characters of a word with *, you can use vegr* with the cursor on the first character of a word.
