1. who are you www.cmd5.com www.xmd5.org www.xmd5.com
2. Please search RSA, DES algorithm
3. Yes, like MD5, it is an irreversible encryption algorithm
collision comparison of safety:
MD5 is 2 ^ 64, SHA1 is 2 ^ 60. So you may not understand. Generally speaking, two MD5 values with the same value can be found in every 2 ^ 64 samples. SHA1 is similar. But this is only a theory. The actual sample is much smaller than this value
now MD5 and SHA1 encryption are cracked by brute force. Even if you can't get your original string, it's easy to get it out.

4. Algorithm, also known as secure hash encryption technology, is the first encryption algorithm in the world. It is mainly used for file identification, digital signature and password encryption
for plaintext information a, a 160 bit identification code B is generated by SHA1 algorithm. The following conditions are satisfied between plaintext information a and identification code B:
1. For any two different plaintext information A1 and A2, the identification codes B1 and B2 are different
2. Plaintext information a cannot be inverted from identification code B through reverse algorithm
the user password of mooncrm is encrypted by SHA1, that is, the server only stores the identification code generated by the user password, but the user password itself is not stored on the server. When the user enters the login password, the system will generate the corresponding identification code according to the input password and compare it with the identification code stored in the system. If the two are consistent, the password is considered correct. The original password value of the user is not stored in the system. Even if someone obtains the password file, the user login password cannot be cracked to ensure the absolute security of the user password.

5. At present, there is no efficient and simple method that can work at one try.
this is equivalent to a theoretical challenge to the cryptographic system in the United States...
and those who have this method will get a large amount of technology reward...
and you can say thank you at most

6. Crack the wireless professional system back track 5, run with a virtual machine or Android system
7. Both SHA1 and MD5 are irreversible hashes
SHA1 is stronger than MD5 and can only be cracked by violence!

10. Algorithm, also known as secure hash encryption technology, is the first encryption algorithm in the world. It is mainly used for file identification, digital signature and password encryption. For plaintext information a, a 160 bit identification code B is generated by SHA1 algorithm. And the plaintext information a and identification code B meet the following conditions at the same time: 1. For any two different plaintext information A1 and A2, the identification codes B1 and B2 are not the same. 2. The plaintext information a cannot be inverted from the identification code B by the reverse algorithm. The user password of mooncrm is encrypted by SHA1, that is, the server only stores the identification code generated by the user password, but the user password itself is not stored on the server. When the user enters the login password, the system will generate the corresponding identification code according to the input password and compare it with the identification code stored in the system.
