POP3 Login Secure

Demonstrates how to set the POP3 password using a secure string.

This example requires Chilkat v9.5.0.71 or greater.

Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

mailman = Chilkat::CkMailMan.new()

# Imagine we've previously saved our encrypted login and password within a JSON config file
# that contains this:

# {
#   "pop3_login": "D7lnlWY291LKMeChlvQq7N/Tg7ieuSB15a+9Ekyd0R4=",
#   "pop3_password": "5neIq9Jmn0E3p71N6Yc8TA=="
# }

json = Chilkat::CkJsonObject.new()
json.LoadFile("qa_data/passwords/pop3.json")

crypt = Chilkat::CkCrypt2.new()

# These are the encryption settings we previously used to encrypt the credentials within the JSON config file.
crypt.put_CryptAlgorithm("aes")
crypt.put_CipherMode("cbc")
crypt.put_KeyLength(128)
crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex")
crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex")
crypt.put_EncodingMode("base64")

ssLogin = Chilkat::CkSecureString.new()
ssPassword = Chilkat::CkSecureString.new()

# Decrypt to the secure string.  (the strings will still held in memory encrypted, but are now encrypted using
# a randomly generated session key.)
crypt.DecryptSecureENC(json.stringOf("pop3_login"),ssLogin)
crypt.DecryptSecureENC(json.stringOf("pop3_password"),ssPassword)

# Set the POP3 domain, login, and password
mailman.put_MailHost("pop.gmail.com")
mailman.put_PopSsl(true)
mailman.put_MailPort(995)

mailman.put_PopUsername(ssLogin.access())
# Set the PopPassword property via the SetPassword method using the secure string.
mailman.SetPassword("pop3",ssPassword)

# Connect and authenticate..
success = mailman.Pop3Connect()
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

success = mailman.Pop3Authenticate()
if (success != true)
    print mailman.lastErrorText() + "\n";
    exit
end

print "POP3 login successful." + "\n";

numMessages = mailman.GetMailboxCount()
if (numMessages < 0)
    print mailman.lastErrorText() + "\n";
    exit
end

print "Num messages in Inbox = " + numMessages.to_s() + "\n";

mailman.Pop3EndSession()
