1.1 07/12/95 - eay
|
||||
Many thanks to Rhys Weatherley <rweather@us.oracle.com>
|
||||
for pointing out that I was assuming little endian byte
|
||||
order for all quantities what idea actually used
|
||||
bigendian. No where in the spec does it mention
|
||||
this, it is all in terms of 16 bit numbers and even the example
|
||||
does not use byte streams for the input example :-(.
|
||||
If you byte swap each pair of input, keys and iv, the functions
|
||||
would produce the output as the old version :-(.
|
||||
|
||||
1.0 ??/??/95 - eay
|
||||
First version.
