Python module to validate the credentials of a Linux user using the /etc/shadow file

Project description

This is a Python module to validate the credentials of a Linux user using the /etc/shadow file.

Please take a look at the full documentation for how to install and use shadow_auth:

How to use Linux Shadow Authentication:

import shadow_auth

if shadow_auth.validate_with_password("username", "1234"):
    # What to do if the user is valid
    pass

if shadow_auth.validate_with_hash("username", "$1$TrOIigLp$FJg1nUqEQPt4OerLOWzr/1"):
    # What to do if the user is valid
    pass

#Get the algorithm and Salt for a User    
password_info = shadow_auth.get_password_info("username")
# password_info = {
#   "algorithm" = "1",
#   "salt" = "TrOIigLp"
# }

#Generate an MD5 hash
new_md5_hash = shadow_auth.generate_openssl_hash(
    algorithm=shadow_auth.Algorithm.MD5,
    salt="TrOIigLp",
    text="abcd12345",    
)
# new_md5_hash = "$1$TrOIigLp$FJg1nUqEQPt4OerLOWzr/1"

#Generate an SHA-256 hash
new_sha_256_hash = shadow_auth.generate_openssl_hash(
    algorithm=shadow_auth.Algorithm.MD5,
    salt="TrOIigLp",
    text="abcd12345",    
)
# new_sha_256_hash = "$5$TrOIigLp$6usEDvu0NgyuQ/IqQyvSBoP0x2RiNOz5izrMViHwXv2"

#Generate an SHA-512 hash
new_sha_512_hash = shadow_auth.generate_openssl_hash(
    algorithm=shadow_auth.Algorithm.MD5,
    salt="TrOIigLp",
    text="abcd12345",    
)
# new_sha_512_hash = "$6$TrOIigLp$IU0KwZfzVkuLLy/9vMFH1RgOmqE3LAGk0K9/15WOGStkeaN2IWYkY0jzCWHMUcSnnewnt9bOUwD2vStgko79v/"
