Blackberry email account not validating
If you *really* know what you are doing, you may answer the next question with yes. (y/N) y [email protected] ~ $ ls -l message* -rw-rw-r-- 1 alice alice 32 Out 13 -rw-rw-r-- 1 alice alice 678 Out 13 gpg " gpg: WARNING: This key is not certified with a trusted signature!
gpg: There is no indication that the signature belongs to the owner.
So, assuming Alice has GPG installed, she would start by creating her own public/private key pair: [email protected] ~ $ gpg --gen-key gpg (Gnu PG) 1.4.20; Copyright (C) 2015 Free Software Foundation, Inc.
She can, for example, store a copy in a USB drive and print a hardcopy and put it in a safe.
The private key implementation of Open PGP actually contains a complete copy of the public key, so this backup file is enough to recover the key pair.
Restoring the backup is done with the sub 2048R/76E5C437 2017-10-13 [email protected] ~ $ gpg --send-keys 96FE8CE5 gpg: sending key 96FE8CE5 to hkp server [email protected] ~ $ gpg --search-keys 96FE8CE5 gpg: searching for "0x96FE8CE5" from hkp server keys.(1) Alice (Mushroom) flag and sent it via email and/or manually publish it in several servers — the more the better.
Well, Alice uses her own private key to encrypt her important message.
The world just has to use Alice public key to decrypt the message, since it is the only way to decrypt it and only the person with Alice private key could have encrypted it, hence proving that it was Alice that wrote that message.
