+# le
+Simplest shell script for LetsEncrypt free Certificate client
+
+This is a shell version from https://github.com/diafygi/acme-tiny
+
+Pure written in bash, no dependencies to python , acme-tiny or LetsEncrypt official client (https://github.com/letsencrypt/letsencrypt)
+
+Just one script, to issue, renew your certiricates automatically.
+
+Possiblly it's the smallest&easiest&smartest shell script to automatically  issue&renew the free certificates from LetsEncrypt.
+
+
+#Supported OS
+1. Tested on Ubuntu/Debian.
+2. CentOS is Not tested yet, It should work.
+
+
+#How to use
+
+1. Clone this project: https://github.com/Neilpang/le.git
+
+2. Install le:
+```
+./le.sh install
+```
+Which does 2 things:
+* create and copy le.sh to your home dir:  `~/.le`
+All the certs will be placed in this folder.
+* create symbol link: `/bin/le  -> ~/.le/ls.sh`
+
+3. Ok,  you are ready to issue cert now.
+Show help message:
+```
+root@xvm:~# le 
+Usage: issue|renew|renewAll|createAccountKey|createDomainKey|createCSR|install|uninstall
+
+root@xvm:~# le issue
+Usage: /bin/le webroot a.com [www.a.com,b.com,c.com]  [key-length] [cert-file-path] [key-file-path] [reloadCmd]
+
+```
+ 
+# Just issue a cert:
+```
+le issue   /home/wwwroot/aa.com    aa.com    www.aa.com,cp.aa.com
+```
+First argument " /home/wwwroot/aa.com" is the web root folder
+
+Second argument "aa.com" is the domain you want to issue cert for.
+
+Third argument  is the additional domain list you want to use.  Comma sperated list,  Optional.
+
+'You must point and bind all the domains to the same webroot dir:/home/wwwroot/aa.com'
+
+The cert will be placed in `~/.le/aa.com/`
+
+
+The issued cert will be renewed every 50 days automatically.
+
+
+# Issue a cert, and install to apache
+```
+le issue   /home/wwwroot/aa.com    aa.com    www.aa.com,cp.aa.com  2048  /path/to/certfile/in/apache/nginx  /path/to/keyfile/in/apache/nginx   "service apache2 reload"
+```
+This can link the issued cert to the production apache or nginx path.
+Once the cert is renewed,  the apache/nginx will be automatically reloaded by the command: ` service apache2 reload`
+
+
+
+
+#Under the Hood
+
+Use bash to say ACME language directly to Let's encrypt.
