Constructor Detail

MD5

public MD5(java.lang.String stringMD5)

Construct a new MD5 with the given String value.

Parameters:

stringMD5 - A 32-character hex value of an MD5 value.

Throws:

java.lang.IllegalArgumentException - If the given value is not 32 characters.

NumberFormatExcpetion - If the given value does not contain all hexadecimal characters (a-z, A-Z, or 0-9).

Method Detail

hashCode

public int hashCode()

Return a hashcode for this MD5 value. Uses the same algorithm as String.hashCode().

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code that distributes nicely based on this object's content, which makes it suitable for hash tables, etc.

equals

public boolean equals(java.lang.Object obj)

Return true if the given byte[] is identical to this object.

Overrides:

equals in class java.lang.Object

Parameters:

obj - Object to be compared.

Returns:

True if the given object is an MD5 object with the same MD5 value.

computeBufferMD5

public void computeBufferMD5(byte[] data)

Compute MD5 for a byte array.

toHexString

public java.lang.String toHexString()

Return the a 32-character String equal to the hex equivalent of this MD5 value.

Returns:

A 32-character String equal to the hex equivalent of this MD5 value.

toString

public java.lang.String toString()

returns a quasi-readable string representation of this MD5

Overrides:

toString in class java.lang.Object

Returns:

String a quasi-readable string representation of this MD5

computeStreamMD5

public int computeStreamMD5(java.io.InputStream in)
                     throws java.io.IOException

Deprecated. Use computeStreamMD5Ex, which supports file sizes greater than 2GB.

Computes the MD5 of the given input stream.

Parameters:

in - The input stream.
