1 给debian8加密（再IDEA加密）并签名一份“我的私钥”

opensuse13:~ #

opensuse13:~ # gpg -r "debian8" -o FranklinYang.rsa.sec.key.sign.debian8.asc -a --se --cipher-algo IDEA FranklinYang.rsa.sec.key

You need a passphrase to unlock the secret key for

user: "FranklinYang (Encrypt RSA 4096) <andypeker@163.com>"

4096-bit RSA key, ID 276856F7, created 2016-11-25

gpg: IDEA encryption will be used

opensuse13:~ #

或者：

opensuse13:~ #

opensuse13:~ # gpg -a -r "debian8new" -u "FranklinYang" -o FranklinYang.sec.key.3des.sig.asc -se --cipher-algo 3DES FranklinYang.sec.key

You need a passphrase to unlock the secret key for

user: "FranklinYang (Encrypt RSA 4096) <andypeker@163.com>"

4096-bit RSA key, ID 276856F7, created 2016-11-25

gpg: CD540DDF: There is no assurance this key belongs to the named user

pub 2048R/CD540DDF 2016-11-26 debian8new

Primary key fingerprint: 8C29 6680 CD0F 8137 CC4E 77C9 9CF8 559D FE76 1741

Subkey fingerprint: 10DD BA9B BB81 15FE 7196 2F70 0036 4591 CD54 0DDF

It is NOT certain that the key belongs to the person named

in the user ID. If you *really* know what you are doing,

you may answer the next question with yes.

Use this key anyway? (y/N) y
