This method is most preferred because the key comes directly from the user who can see that the key has been successfully uploaded. Some keyservers allow you to paste an ASCII armored version of your public key in order to upload it directly.

4) Making an ASCII armored version of your public key If the -output option is omitted, the result will be placed on standard output. Store it where others can't access it because anybody having access to it can revoke your key, rendering it useless. It must be a key specifier, either the key ID of your primary keypair or any part of a user ID that identifies your keypair like The generated certificate will be saved in revoke_key.asc file. You need a passphrase to unlock the secret key for Reason for revocation: No reason specified Sec 4096R/BAC361F1 my_name (my-key-pair) Ĭreate a revocation certificate for this key? (y/N) yĮnter an optional description end it with an empty line: $ gpg -output revoke_key.asc -gen-revoke BAC361F1 The process requires your private key, passphrase. # rngd -f -r /dev/urandom 3) Generating a revocation certificateĪfter your keypair is created you should immediately generate a revocation certificate to revoke your public key if your private key has been compromised in any way or if you lose it. In certain distributions, you need to use rngd before the gpg process. We have only installed it without anything else. Now can start again with the gpg -gen-key command and the process will be fine. # cat /proc/sys/kernel/random/entropy_avail

We can install a package to solve the lack of entropy with rngd which is a random number generator utility used to check immediately the available entropy # apt-get install rng-tools So cancel the process and check the available entropy $ cat /proc/sys/kernel/random/entropy_avail The problem is caused by the lack of entropy (or random system noise). The OS a chance to collect more entropy! (Need 285 more bytes)" Your prompt can be handled for a very long time without finishing if you see the message below "Not enough random bytes available. sub: It represents subkeys, goes along with the primary key.We will use its value to do some operation. uid: Please take a note about the USER-ID mentioned in the result.We need to generate a lot of random bytes. You need a Passphrase to protect your secret key. GnuPG needs to construct a user ID to identify your key. Please specify how long the key should be valid. GPG is able to create several types of keypairs, but a primary key must be capable of making signatures. To encrypt your communication, the first thing to do is to create a new keypair.
