A DESCRIPTION OF THE PROBLEM :
SHA-1 digest function (and maybe other function, I've tested only SHA-1) seems to be broken using a quite large file (I have tested a ~600MB file) with OracleUCrypto provider (hardware implementation) and sparcv9 64-bit jvm.

This is the only combination that produces a wrong hash. Using OracleUCrypto with 32-bit jvm works ok, the same using SUN provider (software implementation) with both 64-bit or 32-bit jvm.

This is the code I've tested:

File f = new File( " largefile " );
FileInputStream fis = new FileInputStream();
byte[] buffer = new byte[(int)f.length()];
fis.read(buffer);

MessageDigest md = MessageDigest.getInstance( " SHA-1 " , " OracleUcrypto " );
byte[] hash = md.digest(buffer); // WRONG HASH!


Another thing I've noticed is that processing digest in streaming works ok:

File f = new File( " largefile " );
FileInputStream fis = new FileInputStream();
byte[] buffer = new byte[(int)f.length()];
fis.read(buffer);

ByteArrayInputStream bais = new ByteArrayInputStream(buf);
int ch;
MessageDigest md = MessageDigest.getInstance( " SHA-1 " , " OracleUcrypto " );
DigestInputStream dis= new DigestInputStream(bais, md);
buffer = new byte[10*1024*1024];
while ((ch = dis.read(buffer)) != -1);

byte[] hash = md.digest(); // OK!


It seems like Ucrypto has problem processing large byte array ...

Thanks
