base64 decoding

Hi,

 

I want to base64 decode a 24 character string to a 32 Hex string.

 

b64decode transfoms the string to a 16 Byte long string

 

To convert it to the 32 Hex values I use the TCL command

 

binary scan $v2 H* v3

 

Example:

 

set v1 6LCnVil6ib5Df9+6JFiW5A==

 

set v2 [b64decode $v1]

 

binary scan $v2 H* v3

 

log $v3

 

 

v3 has the value

 

2756297a89be437ffa245896e4

 

it should have:

 

e8b0a756297a89be437fdfba245896e4

 

binary scan does not work correct.

 

For some values it works.

 

Is there another way to do the conversion?

 

 

regards,

 

Oliver
