| Field Summary | |
| final protected static int | TIMEOUT_INFINITE
Indicates that no once tokens are used only once. | | final protected static int | USE_NEVER_EXPIRES
Indicates that no once tokens are used only once. | | final protected static int | USE_ONCE
Indicates that no once tokens are used only once. | | final protected static String | info
Descriptive information about this implementation. | | protected String | key
Private key. | | final protected static MD5Encoder | md5Encoder
The MD5 helper object for this class. | | protected static MessageDigest | md5Helper
MD5 message digest provider. | | protected long | nOnceTimeout
No once expiration (in millisecond). | | protected Hashtable | nOnceTokens
No once hashtable. | | protected int | nOnceUses
No once expiration after a specified number of uses. |
| TIMEOUT_INFINITE | | final protected static int TIMEOUT_INFINITE(Code) | | Indicates that no once tokens are used only once.
|
| USE_NEVER_EXPIRES | | final protected static int USE_NEVER_EXPIRES(Code) | | Indicates that no once tokens are used only once.
|
| USE_ONCE | | final protected static int USE_ONCE(Code) | | Indicates that no once tokens are used only once.
|
| info | | final protected static String info(Code) | | Descriptive information about this implementation.
|
| md5Encoder | | final protected static MD5Encoder md5Encoder(Code) | | The MD5 helper object for this class.
|
| nOnceTimeout | | protected long nOnceTimeout(Code) | | No once expiration (in millisecond). A shorter amount would mean a
better security level (since the token is generated more often), but at
the expense of a bigger server overhead.
|
| nOnceUses | | protected int nOnceUses(Code) | | No once expiration after a specified number of uses. A lower number
would produce more overhead, since a token would have to be generated
more often, but would be more secure.
|
| DigestAuthenticator | | public DigestAuthenticator()(Code) | | |
| authenticate | | public boolean authenticate(HttpRequest request, HttpResponse response, LoginConfig config) throws IOException(Code) | | Authenticate the user making this request, based on the specified
login configuration. Return true if any specified
constraint has been satisfied, or false if we have
created a response challenge already.
Parameters:
request - Request we are processing
Parameters:
response - Response we are creating
Parameters:
login - Login configuration describing how authenticationshould be performed
exception:
IOException - if an input/output error occurs |
| findPrincipal | | protected static Principal findPrincipal(HttpServletRequest request, String authorization, Realm realm)(Code) | | Parse the specified authorization credentials, and return the
associated Principal that these credentials authenticate (if any)
from the specified Realm. If there is no such Principal, return
null.
Parameters:
request - HTTP servlet request
Parameters:
authorization - Authorization credentials from this request
Parameters:
login - Login configuration describing how authenticationshould be performed
Parameters:
realm - Realm used to authenticate Principals |
| generateNOnce | | protected String generateNOnce(HttpServletRequest request)(Code) | | Generate a unique token. The token is generated according to the
following pattern. NOnceToken = Base64 ( MD5 ( client-IP ":"
time-stamp ":" private-key ) ).
Parameters:
request - HTTP Servlet request |
| getInfo | | public String getInfo()(Code) | | Return descriptive information about this Valve implementation.
|
| parseUsername | | protected String parseUsername(String authorization)(Code) | | Parse the username from the specified authorization string. If none
can be identified, return null
Parameters:
authorization - Authorization string to be parsed |
| removeQuotes | | protected static String removeQuotes(String quotedString)(Code) | | Removes the quotes on a string.
|
| setAuthenticateHeader | | protected void setAuthenticateHeader(HttpServletRequest request, HttpServletResponse response, LoginConfig config, String nOnce)(Code) | | Generates the WWW-Authenticate header.
The header MUST follow this template :
WWW-Authenticate = "WWW-Authenticate" ":" "Digest"
digest-challenge
digest-challenge = 1#( realm | [ domain ] | nOnce |
[ digest-opaque ] |[ stale ] | [ algorithm ] )
realm = "realm" "=" realm-value
realm-value = quoted-string
domain = "domain" "=" <"> 1#URI <">
nonce = "nonce" "=" nonce-value
nonce-value = quoted-string
opaque = "opaque" "=" quoted-string
stale = "stale" "=" ( "true" | "false" )
algorithm = "algorithm" "=" ( "MD5" | token )
Parameters:
request - HTTP Servlet request
Parameters:
resonse - HTTP Servlet response
Parameters:
login - Login configuration describing how authenticationshould be performed
Parameters:
nOnce - nonce token |
