Field Detail

UTIL_HASH

public static final int UTIL_HASH

Hash algorithm. It is really the number of rounds performed. The number of rounds in either the 'encryption' hashing or the WPCODE hashing. The selection of these values is steeped in mystery. They appear to be primarily easy to type.

Constructor Detail

AceF2

public AceF2(int iHashType)

Constructor for AceF2

Parameters:

iHashType - int The type of hash to use; equal to the number of rounds.

Method Detail

setType

public void setType(int iHashType)

Change the type of hash on the fly.

Parameters:

iHashType - int The type of hash to use; equal to the number of rounds.

hash

public byte[] hash(int outLen,
                   byte[] in)
            throws java.security.GeneralSecurityException

This is a variant of the hash function which allocates and return the output buffer to the caller.

Parameters:

outLen - int Length of the desired output.

in - byte[] Input buffer.

Returns:

byte[] Output buffer.

Throws:

java.security.GeneralSecurityException

hash

public void hash(byte[] out,
                 byte[] in)
          throws java.security.GeneralSecurityException

This is the core F2 ACE Hash function. It is passed the input and output buffers and the number of rounds that should be performed.

This function is generally accessed by either sdi_utl_hash() or sdi_int_f2hash() methods.

Parameters:

out - Output byte buffer.

in - Input byte buffer.

count - The number of F2 rounds that should be performed.

Throws:

AceF2Exception - Is thrown for invalid parameters.

java.security.GeneralSecurityException
