[英]What "flavour" of Argon2 is used by python module argon2-cffi?
Argon2 v1.3 is the algorithm used by python module argon2-cffi
. Argon2 v1.3 是 python 模块
argon2-cffi
使用的算法。
In the documentation they state the following:在文档中他们 state 如下:
"argon2-cffi implements Argon2 version 1.3, as described in in: Argon2: the memory-hard function for password hashing and other applications ."
“argon2-cffi 实现 Argon2 版本 1.3,如: Argon2:用于密码散列和其他应用程序的内存硬 function 中所述。”
Yet this document does not specify the actual use of any "flavour" (i/d/id), it just explains the differences.然而,本文档没有具体说明任何“风味”(i/d/id)的实际用途,它只是解释了不同之处。
What "flavour" is used by argon2-cffi
by default? argon2-cffi
默认使用什么“风味”? Is there a way to specify the "flavour" you want to use?有没有办法指定您要使用的“风味”?
Judging from the return value of the hash
function in class PasswordHasher
from argon2-cffi
, it appears it can be concluded that the hybrid "flavour" is used by default.从
argon2-cffi
的 class PasswordHasher
中hash
function 的返回值来看,似乎可以断定,hybrid "fl"默认使用
from argon2 import PasswordHasher
PasswordHasher().hash("foo")
Returns:回报:
"$argon2id$v=19$m=65536,t=3,p=4$xIu1KPUI7Ofe6HxYhmbNiA$6q7HjVOe6933Ogaw0f7pLodCdBgJsST8JAszTkv4Jh4"
This is confirmed by the comment in said class: class 中的评论证实了这一点:
Uses Argon2\ **id** by default and always uses a random salt_ for hashing.
默认使用 Argon2\ **id** 并始终使用随机 salt_ 进行散列。 But it can verify any type of Argon2 as long as the hash is correctly encoded.
但只要 hash 编码正确,它就可以验证任何类型的Argon2 。
Changing the "flavour" used by the module is done by assigning the variable type
of class PasswordHasher
to a Type
class defined in like so:通过将 class
PasswordHasher
的变量type
分配给如下定义的Type
class 来更改模块使用的“风味”:
from argon2 import PasswordHasher, Type
PasswordHasher(type=Type.I).hash("foo") # lib.Argon2_i
PasswordHasher(type=Type.D).hash("foo") # lib.Argon2_d
PasswordHasher(type=Type.ID).hash("foo") # lib.Argon2_id
Each of these Type
variables reference a corresponding argon2 library, shown in comments.这些
Type
变量中的每一个都引用了相应的 argon2 库,如注释中所示。
