代码如下:
from
hashlib
import
md5
def
calMD5(str):
m
=
md5()
m.update(str)
return
m.hexdigest()
def
calMD5ForFile(file):
m
=
md5()
a_file
=
open(file,
'
rb
'
)
m.update(a_file.read())
a_file.close()
return
m.hexdigest()
def
calMD5ForFolder(dir,MD5File):
import
os
outfile
=
open(MD5File,
'
w
'
)
for
root, subdirs, files
in
os.walk(dir):
for
file
in
files:
filefullpath
=
os.path.join(root,file)
print
filefullpath
filerelpath
=
os.path.relpath(filefullpath,dir)
md5
=
calMD5ForFile(filefullpath)
outfile.write(filerelpath
+
'
'
+
md5
+
'
\n
'
)
outfile.close()
print
calMD5(
'
This is one test string
'
)
print
calMD5ForFile(
'
c:\\test\\mytest.txt
'
)
calMD5ForFolder(
'
c:\\test
'
,
'
c:\\mdfile.md5
'
)
