- Throws:
InvalidBERException
-
readFully
public static void readFully(byte[] bytes, java.io.InputStream istream) throws java.io.IOException
Fills a byte array with bytes from an input stream. This method keeps reading until the array is filled, an IOException occurs, or EOF is reached. The byte array will be completely filled unless an exception is thrown.- Parameters:
bytes
- A byte array which will be filled up.istream
- The input stream from which to read the bytes.- Throws:
java.io.IOException
- If an IOException occurs reading from the stream, or EOF is reached before the byte array is filled.

getECCurveBytesByX509PublicKeyBytes
public static byte[] getECCurveBytesByX509PublicKeyBytes(byte[] X509PubKeyBytes, boolean withHeader) throws java.lang.IllegalArgumentException, java.lang.ArrayIndexOutOfBoundsException, java.lang.NullPointerException
returns the ECC curve byte array given the X509 public key byte array- Parameters:
X509PubKeyBytes
- byte array of an X509PubKeywithHeader
- tells if the return byes should inclulde the tag and size header or not- Returns:
- ECC curve byte array.
- Throws:
java.lang.IllegalArgumentException
java.lang.ArrayIndexOutOfBoundsException
java.lang.NullPointerException
-
getOIDdescription
public static java.lang.String getOIDdescription(byte[] oidBA)
getOIDdescription() returns a text description of the OID from OID byte array the OID byte array is expected to be without the OID Tag (6) and size (together 2 bytes)- Parameters:
oidBA
- OID byte array.- Returns:
- OID description.
