Hi guys,
Hi have a little problem with md5 digest.I want to translate in bash language this function in python:

digest = int(md5(value).hexdigest(),16)

(it's an md5 update)

how i "translate" this function in bash or openssl utility in bash?
Thanks

Roughly?

digest=$( echo "ibase=16; $( echo $value | md5sum | cut -f1 -d ' ' | tr '[a-z]' '[A-Z]' )" | bc )

Thanks but not the same result:(
For example

echo -n "0011223344556677889910111213141516171819"|md5sum| cut -f1 -d ' ' | tr '[a-z]' '[A-Z]' | bc
19498340999655919679390993985391

and the pyton gives:

digest = int(md5(0011223344556677889910111213141516171819).hexdigest(),16)
37615660562377680210092719805016069009

whats the matter??

It's because you didn't specify the input base. Compare

$ echo -n "0011223344556677889910111213141516171819" | md5sum | cut -f1 -d ' ' | tr '[a-z]' '[A-Z]' | bc
19498340999655919679390993985391
$ ( echo "ibase=16"; echo -n "0011223344556677889910111213141516171819" | md5sum | cut -f1 -d ' ' | tr '[a-z]' '[A-Z]' ) | bc
37615660562377680210092719805016069009

From man man bc (Linux) (emphasis added)

That means that, with an ibase default of 10, A-F are changed to the number 9:

$ echo -n "0011223344556677889910111213141516171819" | md5sum | cut -f1 -d ' ' | tr '[a-z]' '[A-Z]'
