but the real (fake) truth about that post is here :

I tend to believe more NetAPP in this case, just because i don’t know how many time i have sweared on that bloody ps -aux that does not work on solaris.

# /* Then just as many characters of the MD5(pw,salt,pw) */
mixin = md5.md5(password + salt + password).digest()
for i in range(0, len(password)):
m.update(mixin[i % 16])

# /* Then something really weird... */
# Also really broken, as far as I can tell. -m
i = len(password)
while i:
if i & 1:
m.update('x00')
else:
m.update(password[0])
i >>= 1

final = m.digest()
# /* and now, just to make sure things don't run too fast */
for i in range(1000):
m2 = md5.md5()
if i & 1:
m2.update(password)
else:
m2.update(final)
if i % 3:
m2.update(salt)
if i % 7:
m2.update(password)

if i & 1:
m2.update(final)
else:
m2.update(password)

final = m2.digest()

# This is the bit that uses to64() in the original code.
itoa64 = './0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
rearranged = ''
for a, b, c in ((0, 6, 12), (1, 7, 13), (2, 8, 14), (3, 9, 15), (4, 10, 5)):
v = ord(final[a]) < < 16 | ord(final[b]) << 8 | ord(final[c])
for i in range(4):
rearranged += itoa64[v & 0x3f]; v >>= 6

v = ord(final[11])
for i in range(2):
rearranged += itoa64[v & 0x3f]; v >>= 6

return magic + salt + '$' + rearranged

[/code]

You need to feed it up with a salt, like this :
[code lang="python"]
def generate_salt(count):
import random, string
char = string.ascii_letters + string.digits + string.punctuation.replace(':', '')
return string.join(map(lambda x,v=char: random.choice(v), range(count)), '')
[/code]

I wonder why everything is not as simple as linux thought where we
have everything in one place with /etc/ld.so.config
