This question already has an answer here:

I need to send 10 accounts login data via email, if i send it to a mac user a make an encrypted .dmg file, but as far as I know windows needs a third party app to open .dmg files.

Is it possible to make a .iso with password protection? Is .rar or .zip file password protection safe?

  • What data? do you mean username + password. If you send this in a password protected file, how are you sending the password to that file? – daniel Mar 31 '17 at 9:35
  • Is Excel file with 10 account inside. I can send password to open the file via phone. I edited my question – al404IT Mar 31 '17 at 9:36
  • Yea that sounds OK, a password protected .zip should be ok. I think a .7z can work on Mac and Windows. – daniel Mar 31 '17 at 9:38

    You are essentially asking about how to encrypt files. That you want to sent this encrypted files then with email is just an unimportant detail. Thus possible duplicate of Are password-protected ZIP files secure?, How secure is 7z encryption? and various others. – Steffen Ullrich Mar 31 '17 at 9:41

It as everytime depends on the password too. A password protected .zip file should be fine. Another option would be to create a vera crypt file you can send via E-Mail if its small enough , too.

  • There are different types of zip encriptions and some of them are not fine at all! – Josef Mar 31 '17 at 10:29
  • Wasn't sure about that , thanks for the comment. But truecrypt files should work – Dr3xler Mar 31 '17 at 10:30
  • when given the choice I would chose something like rar or 7z, one of the compression files that have been shown to be hard to brake. Even better would be something like pgp / gpg but thats a whole different toolchain. – LvB Mar 31 '17 at 11:30
