Choose a strong password that will be used for note encryption. The receiver must know this password to read the note.
Note will be deleted if not read within the specific time frame. Note will be deleted after the first read anyways.
Extend AES encryption key to 256 bit, number of PBKDF2 iterations to 1024, length of password to 32 symbols, length of note ID to 12 symbols. Such mode is not necessary, because even without it, note is encrypted secure enough (AES 128 bit).
Generate human-read note URL. This is comfortable to voice or reproduce over devices. Such option is useful if complied with Custom Encryption Password.
Compress the note before encryption. This can greatly increase note loading speed with big text size and slow-speed internet.
Protect note content from copying to clipboard or saving to file by recipient.
