You can  slice  a string very easily  just like you d pull items from a list   a string    This is a string    To get the first 4 letters   first four letters   a string  4   gt  gt  gt   This    Or the last 5   last five letters   a string -5    gt  gt  gt   string    So applying that logic to your problem   the string    416d76b8811b0ddae2fdad8f4721ddbe d4f656ee006e248f2f3a8a93a8aec5868788b927 12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f   first 32 chars   the string  32   gt  gt  gt  416d76b8811b0ddae2fdad8f4721ddbe

Since there is a delimiter  you should use that instead of worrying about how long the md5 is    gt  gt  gt  s    416d76b8811b0ddae2fdad8f4721ddbe d4f656ee006e248f2f3a8a93a8aec5868788b927 12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f   gt  gt  gt  md5sum  delim  rest   s partition       gt  gt  gt  md5sum  416d76b8811b0ddae2fdad8f4721ddbe    Alternatively   gt  gt  gt  md5sum  sha1sum  sha5sum   s split       gt  gt  gt  md5sum  416d76b8811b0ddae2fdad8f4721ddbe   gt  gt  gt  sha1sum  d4f656ee006e248f2f3a8a93a8aec5868788b927   gt  gt  gt  sha5sum  12a5f648928f8e0b5376d2cc07de8e4cbf9f7ccbadb97d898373f85f0a75c47f
