I have a script that runs the grub-md5-crypt command based on whether the pass_value variable is a non-zero string. The md5 hash is being created in the /opt/hostconfigs/$HOST file, but I can't echo $md5_value. It is blank. Is there a way to create and echo a md5 hash variable?

hi
i want to generate MD5 hash of string in unix (hp) i have the algorithm which takes file as argument and returns hash of file but when i tried to generate hash of "a" result was "60b725f10c9c85c70d97880dfe8191b3" hash but actually it should have been "0cc175b9c0f1b6a831c399e269772661" now i...

I am a newbie to shell programming. Can someone help me with the following ?
Shell script that accomplishes the following -

# Step 2 Loop through each filename say a.htm and MD5 hash the filename to say b.htm
# Step 3 copy a.htm to b.htm

I am trying to use John the Ripper but it doesn't take regular MD5 hashes, only shadow MD5 hashes. For example this hash: 900150983cd24fb0d6963f7d28e17f72 (which, decrypted, is 'abc') within a text file, John the Ripper does not detect because it is not in shadow format. How can I convert this MD5... (2 Replies)
Hello everyone,
I am looking to basically creating md5sum files for all iso files in a directory and archive the resulting md5 files into a single archive in that very same directory.
I worked out a clumsy solution such as:
#find files for which md5sum are to be created and store the... (1 Reply)
I have a .csv file and I want to md5 hash the second column for each row in the file.
File is something like
data1,foobar1,123,345
data2,foobar2,456,9393
data3,foobar3,1002,10109
Output would be like

bio_pop
BIO_push(3) OpenSSL BIO_push(3)NAME
BIO_push, BIO_pop - add and remove BIOs from a chain.
SYNOPSIS
#include <openssl/bio.h>
BIO * BIO_push(BIO *b,BIO *append);
BIO * BIO_pop(BIO *b);
DESCRIPTION
The BIO_push() function appends the BIO append to b, it returns b.
BIO_pop() removes the BIO b from a chain and returns the next BIO in the chain, or NULL if there is no next BIO. The removed BIO then
becomes a single BIO with no association with the original chain, it can thus be freed or attached to a different chain.
NOTES
The names of these functions are perhaps a little misleading. BIO_push() joins two BIO chains whereas BIO_pop() deletes a single BIO from a
chain, the deleted BIO does not need to be at the end of a chain.
The process of calling BIO_push() and BIO_pop() on a BIO may have additional consequences (a control call is made to the affected BIOs) any
effects will be noted in the descriptions of individual BIOs.
EXAMPLES
For these examples suppose md1 and md2 are digest BIOs, b64 is a base64 BIO and f is a file BIO.
If the call:
BIO_push(b64, f);
is made then the new chain will be b64-chain. After making the calls
BIO_push(md2, b64);
BIO_push(md1, md2);
the new chain is md1-md2-b64-f. Data written to md1 will be digested by md1 and md2, base64 encoded and written to f.
It should be noted that reading causes data to pass in the reverse direction, that is data is read from f, base64 decoded and digested by
md1 and md2. If the call:
BIO_pop(md2);
The call will return b64 and the new chain will be md1-b64-f data can be written to md1 as before.
RETURN VALUES
BIO_push() returns the end of the chain, b.
BIO_pop() returns the next BIO in the chain, or NULL if there is no next BIO.
