I heard that yesterday is the Singles Day (11.11), a depressed and frustrated day! The mobile phone was taken away (although it has been broken), a credit card (not opened) and three savings cards were filled, and they were also integrated. To have multiple back! Bitter ~
In life, we often need to remember a lot of passwords and save some important information (such as credit card password, savings account, password, telephone account password, social security account, etc.) for security us, it is best to use different passwords, but to remember these differences The password is not an easy thing to do with the accounts. It is easy to write a password manager software, so you can manage multiple passwords and important information through a password. Of course, put all the eggs in one. The basket is quite risky, but you can reduce this risk caused by the main password by some details. First, it is necessary to ensure that this master password cannot be used elsewhere to reduce the chance of leakage of the master password, and use one information hidden technology within the software to further protect confidential information. Such information hiding technology is a technique that freely affects the protected information without affecting host information, such as attaching a ciphertext in a normal picture, and guaranteeing the normal readable, and even keep the picture file. The size is not changed, and the information hidden in the picture can be obtained by stripping.
