I want to convert 160-bit to integer

问题

I am using SHA1 so i want to convert the output of this SHA1 to integer

回答1:

How about

echo preg_replace("/[^0-9]/i", "", sha1("apikot"));

回答2:

You could represent 160 bits in 5 long ints. That could be an array of 5 long ints, or you could have it be an array of 10 short ints. Are you trying to make it easier to handle than a string of characters/bits?

回答3:

This will convert the sha1sum of /tmp/a to a decimal integer:

$ (echo ibase=16; (cat /tmp/a | sha1sum | tr a-z A-Z | sed s/-// )) | bc
