|
## Quick How-To
|
|
|
|
|
|
|
|
|
|
Codecrypt uses hash-based signatures (FMTSeq) and McEliece code-based
|
|
|
|
|
encryption (McE-quasidyadic).
|
|
|
|
|
|
|
|
|
|
Everything is meant to work mostly like GnuPG, but with some good simplicity margin. Let's play with random data!
|
|
|
|
|
|
|
|
|
|
ccr -g help
|
|
|
|
|
ccr -g fmtseq128 --name "John Doe" # your signature key
|
|
|
|
|
ccr -g mceqd128 --name "John Doe" # your encryption key
|
|
|
|
|
|
|
|
|
|
ccr -K #watch the generated keys
|
|
|
|
|
ccr -k
|
|
|
|
|
|
|
|
|
|
ccr -p -a -o my_pubkeys.asc # and send it to friends
|
|
|
|
|
|
|
|
|
|
#see what people sent us
|
|
|
|
|
ccr -ina < friends_pubkeys.asc
|
|
|
|
|
|
|
|
|
|
#import Frank's key and rename it
|
|
|
|
|
ccr -i -R friends_pubkeys.asc --name "Friendly Frank"
|
|
|
|
|
|
|
|
|
|
#send a nice message to Frank (you can also specify him by @12345 keyid)
|
|
|
|
|
ccr -se -r Frank < Document.doc > Message_to_frank.ccr
|
|
|
|
|
|
|
|
|
|
#receive a reply
|
|
|
|
|
ccr -dv -o Decrypted_verified_reply.doc <Reply_from_frank.ccr
|
|
|
|
|
|
|
|
|
|
#rename other's keys
|
|
|
|
|
ccr -m Frank -N "Unfriendly Frank"
|
|
|
|
|
|
|
|
|
|
#and delete pukeys of everyone who's Unfriendly
|
|
|
|
|
ccr -x Unfri
|
|
|
|
|
|
|
|
|
|
