galaxy.security.object_wrapper.wrap_with_safe_string(value, no_wrap_classes=None)

Recursively wrap values that should be wrapped.

class galaxy.security.object_wrapper.SafeStringWrapper(*arg, **kwd)

Bases: object

Class that wraps and sanitizes any provided value’s attributes that will attempt to be cast into a string.

Attempts to mimic behavior of original class, including operands.

To ensure proper handling of e.g. subclass checks, the wrap_with_safe_string() method should be used.

This wrapping occurs in a recursive/parasitic fashion, as all called attributes of the originally wrapped object will also be wrapped and sanitized, unless the attribute is of a type found in __DONT_SANITIZE_TYPES__ + __DONT_WRAP_TYPES__, where e.g. ~(strings will still be sanitized, but not wrapped), and e.g. integers will have neither.

__init__(value, safe_string_wrapper_function=<function wrap_with_safe_string>)

class galaxy.security.object_wrapper.CallableSafeStringWrapper(*arg, **kwd)

Bases: SafeStringWrapper

galaxy.security.passwords module

galaxy.security.passwords.hash_password(password)

galaxy.security.passwords.hash_password_PBKDF2(password)

galaxy.security.passwords.check_password_PBKDF2(guess, hashed)

galaxy.security.passwords.pbkdf2_bin(data, salt, iterations=100000, keylen=24, hashfunc='sha256')

Returns a binary digest for the PBKDF2 hash algorithm of data with the given salt. It iterates iterations time and produces a key of keylen bytes. By default SHA-256 is used as hash function, a different hashlib hashfunc can be provided.

galaxy.security.ssh_util module

class galaxy.security.ssh_util.SSHKeys(private_key, public_key, private_key_file, public_key_file)

galaxy.security.validate_user_input.validate_password_str(password)

galaxy.security.validate_user_input.validate_publicname_str(publicname)

galaxy.security.validate_user_input.transform_publicname(publicname)

Transform publicname to respect the minimum and maximum string length, and the allowed characters. FILL_CHAR is used to extend or replace characters.
