39 | <p>SSL, or Secure Socket Layer, is a technology which allows web browsers and |
---|
40 | web servers to communicate over a secured connection. This means that the data |
---|
41 | being sent is encrypted by one side, transmitted, then decrypted by the other |
---|
42 | side before processing. This is a two-way process, meaning that both the |
---|
43 | server AND the browser encrypt all traffic before sending out data.</p> |
---|
44 | |
---|
45 | <p>Another important aspect of the SSL protocol is Authentication. This means |
---|
46 | that during your initial attempt to communicate with a web server over a secure |
---|
47 | connection, that server will present your web browser with a set of |
---|
48 | credentials, in the form of a "Certificate", as proof the site is who and what |
---|
49 | it claims to be. In certain cases, the server may also request a Certificate |
---|
50 | from your web browser, asking for proof that <em>you</em> are who you claim |
---|
51 | to be. This is known as "Client Authentication," although in practice this is |
---|
52 | used more for business-to-business (B2B) transactions than with individual |
---|
53 | users. Most SSL-enabled web servers do not request Client Authentication.</p> |

57 | <p>It is important to note that configuring Tomcat to take advantage of |

58 | secure sockets is usually only necessary when running it as a stand-alone |
---|
59 | web server. When running Tomcat primarily as a Servlet/JSP container behind |
---|
60 | another web server, such as Apache or Microsoft IIS, it is usually necessary |
---|
61 | to configure the primary web server to handle the SSL connections from users. |
---|
62 | Typically, this server will negotiate all SSL-related functionality, then |
---|
63 | pass on any requests destined for the Tomcat container only after decrypting |
---|
64 | those requests. Likewise, Tomcat will return cleartext responses, that will |
---|
65 | be encrypted before being returned to the user's browser. In this environment, |
---|
66 | Tomcat knows that communications between the primary web server and the |
---|
67 | client are taking place over a secure connection (because your application |
---|
68 | needs to be able to ask about this), but it does not participate in the |

72 | |
---|
73 | <p>In order to implement SSL, a web server must have an associated Certificate |
---|
74 | for each external interface (IP address) that accepts secure connections. |
---|
75 | The theory behind this design is that a server should provide some kind of |
---|
76 | reasonable assurance that its owner is who you think it is, particularly |
---|
77 | before receiving any sensitive information. While a broader explanation of |
---|
78 | Certificates is beyond the scope of this document, think of a Certificate |
---|
79 | as a "digital driver's license" for an Internet address. It states what |
---|
80 | company the site is associated with, along with some basic contact |
---|
81 | information about the site owner or administrator.</p> |
---|
82 | |
---|
83 | <p>This "driver's license" is cryptographically signed by its owner, and is |
---|
84 | therefore extremely difficult for anyone else to forge. For sites involved |
---|
85 | in e-commerce, or any other business transaction in which authentication of |
---|
86 | identity is important, a Certificate is typically purchased from a well-known |
---|
87 | <em>Certificate Authority</em> (CA) such as VeriSign or Thawte. Such |
---|
88 | certificates can be electronically verified -- in effect, the Certificate |
---|
89 | Authority will vouch for the authenticity of the certificates that it grants, |
---|
90 | so you can believe that that Certificate is valid if you trust the Certificate |
---|
91 | Authority that granted it.</p> |
---|
92 | |
---|
93 | <p>In many cases, however, authentication is not really a concern. An |
---|
94 | administrator may simply want to ensure that the data being transmitted and |
---|
95 | received by the server is private and cannot be snooped by anyone who may be |
---|
96 | eavesdropping on the connection. Fortunately, Java provides a relatively |
---|
97 | simple command-line tool, called <code>keytool</code>, which can easily create |
---|
98 | a "self-signed" Certificate. Self-signed Certificates are simply user |
---|
99 | generated Certificates which have not been officially registered with any |
---|
100 | well-known CA, and are therefore not really guaranteed to be authentic at all. |
---|
101 | Again, this may or may not even be important, depending on your needs.</p> |

104 | |
---|
105 | <p>The first time a user attempts to access a secured page on your site, |
---|
106 | he or she is typically presented with a dialog containing the details of |
---|
107 | the certificate (such as the company and contact name), and asked if he or she |
---|
108 | wishes to accept the Certificate as valid and continue with the transaction. |
---|
109 | Some browsers will provide an option for permanently accepting a given |
---|
110 | Certificate as valid, in which case the user will not be bothered with a |
---|
111 | prompt each time they visit your site. Other browsers do not provide this |
---|
112 | option. Once approved by the user, a Certificate will be considered valid |
---|
113 | for at least the entire browser session.</p> |
---|
114 | |
---|
115 | <p>Also, while the SSL protocol was designed to be as efficient as securely |
---|
116 | possible, encryption/decryption is a computationally expensive process from |
---|
117 | a performance standpoint. It is not strictly necessary to run an entire |
---|
118 | web application over SSL, and indeed a developer can pick and choose which |
---|
119 | pages require a secure connection and which do not. For a reasonably busy |
---|
120 | site, it is customary to only run certain pages under SSL, namely those |
---|
121 | pages where sensitive information could possibly be exchanged. This would |
---|
122 | include things like login pages, personal information pages, and shopping |
---|
123 | cart checkouts, where credit card information could possibly be transmitted. |
---|
124 | Any page within an application can be requested over a secure socket by |
---|
125 | simply prefixing the address with <code>https:</code> instead of |
---|
126 | <code>http:</code>. Any pages which absolutely <strong>require</strong> |
---|
127 | a secure connection should check the protocol type associated with the |
---|
128 | page request and take the appropriate action if <code>https</code> is not |
---|
129 | specified.</p> |
---|
130 | |
---|
131 | <p>Finally, using name-based virtual hosts on a secured connection can be |
---|
132 | problematic. This is a design limitation of the SSL protocol itself. The SSL |
---|
133 | handshake, where the client browser accepts the server certificate, must occur |
---|
134 | before the HTTP request is accessed. As a result, the request information |
---|
135 | containing the virtual host name cannot be determined prior to authentication, |
---|
136 | and it is therefore not possible to assign multiple certificates to a single |
---|
137 | IP address. If all virtual hosts on a single IP address need to authenticate |
---|
138 | against the same certificate, the addition of multiple virtual hosts should not |
---|
139 | interfere with normal SSL operations on the server. Be aware, however, that |
---|
140 | most client browsers will compare the server's domain name against the domain |
---|
141 | name listed in the certificate, if any (applicable primarily to official, |
---|
142 | CA-signed certificates). If the domain names do not match, these browsers will |
---|
143 | display a warning to the client user. In general, only address-based virtual |
---|
144 | hosts are commonly used with SSL in a production environment.</p> |

---|
152 | is Java's standard "Java KeyStore" format, and is the format created by the |
---|
153 | <code>keytool</code> command-line utility. This tool is included in the JDK. |

154 | The <code>PKCS12</code> format is an internet standard, and can be manipulated |

157 | |

158 | <p>Each entry in a keystore is identified by an alias string. Whilst many |

159 | keystore implementations treat aliases in a case insensitive manner, case |
---|
160 | sensitive implementations are available. The <code>PKCS11</code> specification, |
---|
161 | for example, requires that aliases are case sensitive. To avoid issues related |

162 | to the case sensitivity of aliases, it is not recommended to use aliases that |

213 | <p>After executing this command, you will first be prompted for the keystore |

214 | password. The default password used by Tomcat is "<code>changeit</code>" |

215 | (all lower case), although you can specify a custom password if you like. |
---|
216 | You will also need to specify the custom password in the |

225 | password specifically for this Certificate (as opposed to any other |

226 | Certificates stored in the same keystore file). You <strong>MUST</strong> |
---|
227 | use the same password here as was used for the keystore password itself. |

258 | SSLRandomSeed allows to specify a source of entropy. Productive system needs a reliable source of entropy |

344 | <p>You will note that the Connector element itself is commented out by default, |
---|
345 | so you will need to remove the comment tags around it. Then, you can |
---|
346 | customize the specified attributes as necessary. For detailed information |
---|
347 | about the various options, consult the |
---|
348 | <a href="../config/index.html">Server Configuration Reference</a>. The |
---|
349 | following discussion covers only those attributes of most interest when |
---|
350 | setting up SSL communication.</p> |
---|
351 | |
---|
352 | <p>The <code>port</code> attribute (default value is 8443) is the TCP/IP |
---|
353 | port number on which Tomcat will listen for secure connections. You can |
---|
354 | change this to any port number you wish (such as to the default port for |
---|
355 | <code>https</code> communications, which is 443). However, special setup |
---|
356 | (outside the scope of this document) is necessary to run Tomcat on port |
---|
357 | numbers lower than 1024 on many operating systems.</p> |
---|
358 | |
---|
359 | <blockquote><em> |
---|
360 | <p>If you change the port number here, you should also change the |
---|
361 | value specified for the <code>redirectPort</code> attribute on the |
---|
362 | non-SSL connector. This allows Tomcat to automatically redirect |
---|
363 | users who attempt to access a page with a security constraint specifying |
---|
364 | that SSL is required, as required by the Servlet 2.4 Specification.</p> |
---|
365 | </em></blockquote> |
---|
366 | |
---|
367 | <p>There are additional options used to configure the SSL protocol. |
---|
368 | You may need to add or change the following attribute |
---|
369 | values, depending on how you configured your keystore earlier:</p> |
