Setup

create dir to store data

   mkdir -p /var/lib/ssl/{private,keys,certs,newcerts,crl,requests}

echo 01 > /var/lib/ssl/serial touch /var/lib/ssl/index.txt

set directory

  • put $dir = /var/lib/ssl/private/ in openssl.cnf

create root cert

openssl req -config /etc/openssl.cnf -new -x509 -keyout /var/lib/ssl/private/cakey.pem -out /var/lib/ssl/certs/cacert.pem

or to init the dir 

   ./CA.pl -newcert

   mv newkey.pem /var/lib/ssl/private/cakey.pem ; mv newcert.pem /var/lib/ssl/certs/cacert.pem

Strip the cert

First strip the certificate from all its text to keep only the -CERTIFICATE- section 

   openssl x509 -in /var/lib/ssl/certs/cacert.pem -out /var/lib/ssl/certs/cacert.crt

Requests

Create requests

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/wwwreq.pem -out /var/lib/ssl/requests/wwwreq.pem

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/www-localreq.pem -out /var/lib/ssl/requests/www-localreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/smtpreq.pem \
               -out /var/lib/ssl/requests/smtpreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/smtp-localreq.pem \
               -out /var/lib/ssl/requests/smtp-localreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/mailreq.pem -out /var/lib/ssl/requests/mailreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/mail-localreq.pem -out /var/lib/ssl/requests/mail-localreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/vpnreq.pem -out /var/lib/ssl/requests/vpnreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/vpn-localreq.pem -out /var/lib/ssl/requests/vpn-localreq.pem 

   openssl req -config /etc/openssl.cnf -new -keyout /var/lib/ssl/requests/maistor-localreq.pem -out /var/lib/ssl/requests/maistor-localreq.pem

       openssl rsa  -in /var/lib/ssl/requests/wwwreq.pem 		-out /var/lib/ssl/keys/www.key
       openssl rsa  -in /var/lib/ssl/requests/www-localreq.pem	-out /var/lib/ssl/keys/www-local.key

view content

       openssl x509 -in www.crt -text

gen dh

       openssl gendh -out /var/lib/ssl/keys/dh2048.key 2048

Access IMAP Server

IMAP Server

Connect the Server

       openssl s_client -crlf -connect imap.gmail.com:993

Login

To login, issue the following command 

       tag login user@gmail.com password

tag before login command is some character sequence required to be used before each subsequent IMAP command. If that works you’ll see an output such as 

       * CAPABILITY IMAP4rev1 UNSELECT IDLE NAMESPACE QUOTA ID XLIST CHILDREN X-GM-EXT-1 UIDPLUS COMPRESS=DEFLATE
       tag OK user@gmail.com User authenticated (Success)

List Mailboxes

Issue the following command 

       tag LIST "" "*"

This produce an output such as 

       * LIST (\HasNoChildren) "/" "INBOX"
       * LIST (\HasNoChildren) "/" "Notes"
       * LIST (\Noselect \HasChildren) "/" "[Gmail]"
       * LIST (\HasNoChildren) "/" "[Gmail]/All Mail"
       * LIST (\HasNoChildren) "/" "[Gmail]/Drafts"
       * LIST (\HasNoChildren) "/" "[Gmail]/Sent Mail"
       * LIST (\HasNoChildren) "/" "[Gmail]/Spam"
       * LIST (\HasNoChildren) "/" "[Gmail]/Starred"
       * LIST (\HasChildren \HasNoChildren) "/" "[Gmail]/Trash"

Select a mailbox

Issue the following command to select the INBOX 

       tag SELECT INBOX

This produces an output such as 

       * FLAGS (\Answered \Flagged \Draft \Deleted \Seen)
       * OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted \Seen \*)]
       * OK [UIDVALIDITY 2]
       * 6385 EXISTS
       * 0 RECENT
       * OK [UIDNEXT 29210]
       tag OK [READ-WRITE] INBOX selected. (Success)

Mailbox status

Execute the following command to get the total number of messages in the selected Mailbox 

       tag STATUS INBOX (MESSAGES)

The result is an output such as 

       * STATUS "INBOX" (MESSAGES 6388)

Fetch headers of last ten messages

Execute the command 

       tag FETCH 6378:6388 (BODY[HEADER])

Fetch message body

Execute the following command 

       tag FETCH 6388 (BODY)

The number 6388 corresponds to the number of the last message above - the first message would be 1, and so on.

Message bodies are usually multipart - you can retrieve a particular part using 

       tag FETCH 6388 (BODY[n])

n is a zero-indexed part number.

Log out

Finally, to close the IMAP session 

       tag LOGOUT
