@Alexandre, All of this is for fun, and I bit someone that I can make good Hand cipher with a good Random Generator, If this is the wrong place to share my Ideas let me know ^_^

@ Ilmari Karonen, i try gpg --use-embedded-filename filename.gpg but it ask for password and not shown the old file name, did u mean 'This defaults to no.' that i should use the option before encrypt the file or it work by default.

comment Is frequency analysis a useful tool against encryption by multiplication?
@fgrieu, what if i multiplying the key by 911*855*552 and use the result as key to encrypt the plain text like one time pad, ex. key= password. 161191923154*911=146845841993294 , then use the numbers to encrypt the plain text and if the numbers shorter than the message i multiplying the result again with another numbers and again until get numbers longer than the message finally use them like otp, is that way secure ?
