implementation of The OAuth 1.0 Protocol.
Components
OAuthBaseString
For building a Signature Base String.
final OAuthBaseString baseString = new OAuthBaseString();
You can use following methods to set values.
baseString.httpMethod(httpMethod);
baseString.baseUri(baseUri);
baseString.queryParameter(key, value);
baseString.protocolParameter(key, value); // key must start with 'oauth_'
baseString.entityParameter(key, value);
OAuthSignature
For generating a Signature.
| class | method | platform |
|---|---|---|
OAuthSignatureHmacSha1Bc |
HMAC-SHA1 |
BC |
OAuthSignatureHmacSha1Jca |
HMAC-SHA1 |
JCA |
OAuthSignatureRsaSha1Bc |
RSA-SHA1 |
BC |
OAuthSignatureRsaSha1Jca |
RSA-SHA1 |
JCA |
OAuthSignaturePlaintext |
PLAINTEXT |
HMAC-SHA1
There are two implementations. One is for Java Cryptograph Architexture and the other is for Legion of the Bouncy Castle.
final OAuthSignatureHmacSha1 signature = new OAuthSignatureHmacSha1Bc(); // BC
final OAuthSignatureHmacSha1 signature = new OAuthSignatureHmacSha1Jca(); // JCA
You can use following methods to set values.
signature.consumerSecret(consumerSecret);
signature.tokenSecret(tokenSecret);
signature.baseString(baseString); // OAuthBaseString
RSA-SHA1
There are, again, two implementations. One is for Java Cryptograph Architexture and the other is for Legion of the Bouncy Castle.
final OAuthSignatureRsaSha1 signature = new OAuthSignatureRsaSha1Bc(); // BC
final OAuthSignatureRsaSha1 signature = new OAuthSignatureRsaSha1Jca(); // JCA
You can use following methods to set values.
signature.initParam(PrivateKey privateKey); // JCA
signature.initParam(CipherParameters cipherParameters); // BC
PLAINTEXT
new OAuthSignaturePlaintext();
OAuthProtocolParameters
final OAuthProtocolParameters protocolParameters = new OAuthProtocolParameters();
protocolParameters.realm(realm);
protocolParameters.signature(signature); // OAuthSignature
Three kinds of output defined in 3.5. Parameter Transmission are supported.
final String header = protocolParameters.authorizationHeader(); // Authorization Header
final String body = protocolParameters.formEncodedBody(); // Form-Encoded Body
final String query = protocolParameters.requestUriQuery(); // Request URI Query
Examples
final OAuthRequest protocolParameters = new OAuthRequest()
.realm("Example")
.signature(
new OAuthSignatureHmacSha1Bc()
.consumerSecret("j49sk3j29djd")
.tokenSecret("dh893hdasih9")
.baseString(
new OAuthBaseString()
.httpMethod("POST")
.baseUri("http://example.com/request")
.queryParameter("b5", "=%3D")
.queryParameter("a3", "a")
.queryParameter("c@", "")
.queryParameter("a2", "r b")
.oauthConsumerKey("9djdj82h48djs9d2")
.oauthNonce("7d8f3e4a")
.oauthTimestamp("137131201")
.oauthToken("kkk9d7dh3k39sjv7")
.entityParameter("c2", "")
.entityParameter("a3", "2 q")
)
);
final String authorizationHeader = protocolParameters.authorizationHeader();
