url
- String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA")
-
TSAClientBouncyCastle
Creates an instance of a TSAClient that will use BouncyCastle.- Parameters:
url
- String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA")username
- String - user(account) namepassword
- String - password
-
TSAClientBouncyCastle
public TSAClientBouncyCastle(String url, String username, String password, int tokSzEstimate, String digestAlgorithm) Constructor. Note the token size estimate is updated by each call, as the token size is not likely to change (as long as we call the same TSA using the same imprint length).- Parameters:
url
- String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA")username
- String - user(account) namepassword
- String - passwordtokSzEstimate
- int - estimated size of received time stamp token (DER encoded)
-
-
Method Details
-
setTSAInfo
- Parameters:
tsaInfo
- the tsaInfo to set
-
getTokenSizeEstimate
public int getTokenSizeEstimate()Get the token size estimate. Returned value reflects the result of the last succesfull call, padded- Specified by:
getTokenSizeEstimate
in interfaceTSAClient
- Returns:
- an estimate of the token size
-
getTSAReqPolicy
-
setTSAReqPolicy
-
getMessageDigest
Gets the MessageDigest to digest the data imprint- Specified by:
getMessageDigest
in interfaceTSAClient
- Returns:
- the digest algorithm name
- Throws:
GeneralSecurityException
-
getTimeStampToken
public byte[] getTimeStampToken(byte[] imprint) throws IOException, org.bouncycastle.tsp.TSPException Get RFC 3161 timeStampToken. Method may return null indicating that timestamp should be skipped.- Specified by:
getTimeStampToken
in interfaceTSAClient
- Parameters:
imprint
- data imprint to be time-stamped- Returns:
- encoded, TSA signed data of the timeStampToken
- Throws:
IOException
org.bouncycastle.tsp.TSPException
-
getTSAResponse
Get timestamp token - communications layer- Returns:
- - byte[] - TSA response, raw bytes (RFC 3161 encoded)
- Throws:
IOException
