IBM 3624 Customer pin,natural pin,pin offset related contentThe following describes how to generate a K-bit user pin using IBM 36241. Use the PIN verification Key (PVK) to encrypt the pan (Primary account number) to the right 16 bits, resulting in a 16-bit hexadecimal string
ANSI X9.8 Standard pin xor pan get pin BlOCKBefore I saw a few introductions, the ANSI is said to be 16 bytes, really rip, all kinds of fraught, the real ANSI algorithm is actually 8 bytes, the specific format is as follows:(1) ANSI X9.8 Format(without master account information)PIN (Personal identification number Personal Identity number) has a total of 8 byte l

An ACL is an abbreviation for Access Control List. The basic purpose is to provide a detailed permission configuration beyond the Read,write,execute permissions of the traditional owner,group,others. ACLs can be used for single-user, single-file or folder-r,w,x permission specifications, which is useful for situations where special permissions are required.What are the main areas in which ACLs can control p
. If there is an X on that bit, then these special flags (SUID, sgid, sticky) are shown as lowercase letters (s, s, t), otherwise they are shown as uppercase letters (s, s, T).

The ACL can be modified with the "setfacl–m" command.Example: Modify the permissions of the instructor user to rwx.
[Email protected] ~]# setfacl-m u:instructor:rwx/home/project/
You can remove a user from an ACL by using the "setfacl-x" command.Example: Remove the instructor user from the ACL.
[Email protected] ~]# setfacl-x u:instructor/home/project/

Zookeeper uses ACLs to control access to nodes, and ACLs are implemented similar to access permissions for UNIX files: use BITS to control the scope and access permissions for node access. But unlike UNIX file systems, for standard scopes, including user (owner of file), group and World (other), zookeeper nodes are not limited. Zookeeper does not have the concept of a znode owner, instead,

USB 3.0 mini interface specifications
To be backward compatible with version 2.0, USB 3.0 adopts a 9-pin design. The four pins have the same shape and definition as USB 2.0, and the other five are specially prepared for USB 3.0, this is also considered a combo solution.

The Linux File System provides the rwx permissions defined by the owner, owning group, and other users (other) for each type of users, and they are independent of each other. Although Linux supports the special file permissions of LinuxPermission control can be precise to users and groups (for example, allowing a file to be modified by a special user and allowing users in a group to view the permissions ).These are obviously not enough. Fortunately, Linux also supports
