Illustratively, each encryption mode is as follows, and the corresponding encryption mode can be selected according to actual needs:
1. base64 encryption mode (reversible)
Printable characters in Base64 included the letters A-Z/a-Z/the array 0-9/plus sign '+' slash '/', thus totaling 62 characters;
base64 ios7 was later added to the system library.
2. MD5 encryption mode
Message Digest Algorithm MD5 (the name of chinese is the fifth version of the Message Digest Algorithm) is a hash function to provide integrity protection for messages, and the process is irreversible because the original plaintext cannot be obtained according to the output value of the Digest Algorithm and the hash Algorithm.
The MD5 algorithm has the following characteristics:
1) compressibility: for any length of data, the calculated length of the MD5 value is fixed.
2) Easy to calculate: it is easy to calculate the MD5 value from the raw data.
3) Resistance to modification: any change to the original data, even if only 1 byte is modified, can result in a great difference in the value of MD 5.
4) Strong collision resistance: knowing the original data and its MD5 value, it is very difficult to find a data with the same MD5 value (i.e., counterfeit data).
MD5 functions to allow large volumes of information to be "compressed" into a secure format (i.e., a string of bytes of arbitrary length is converted into a fixed-length hexadecimal digital string) before the private key is signed by digital signature software. Besides MD5, sha-1, RIPEMD, Haval, MD5, and the like are also known among others.
3. Key string encryption mode
iCloud key string, a sandbox:
1) if the mobile phone is out of the prison, the password is easy to steal.
2) When the software is updated, the content in the sandbox is not deleted. However, if the software is unloaded and reloaded, the data in the sandbox is not available.
3) The sandbox of each APP is relatively independent, and the password cannot be shared.
4. Symmetric encryption algorithm
The advantages are that: the algorithm is open, the calculated amount is small, the encryption speed is high, the encryption efficiency is high, and the method is reversible;
the disadvantages are as follows: the two parties use the same key, and the security is not guaranteed
The current situation is as follows: symmetric encryption is much faster than public key encryption, and symmetric encryption is required in many occasions,
the algorithm commonly used in the symmetric encryption algorithm comprises the following steps: DES, 3DES, TDEA, Blowfish, RC2, RC4, RC5, IDEA, SKIPJACK, AES, etc. Different algorithms have different implementation mechanisms, and details of the corresponding algorithms can be referred to
Compared with DES and 3DES algorithms, AES algorithm has higher speed and resource utilization efficiency, higher security level, and is called next generation encryption standard
nECB: electronic codebooks, that is, each block is independently encrypted;
nCBC: cipher block chain, using a key and an Initialization Vector (IV) to perform a cryptographic transformation on data
ECB and CBC differences: the CBC is more complex and secure, with an 8-bit vector added (8 0 s result in ECB). And a letter is changed in the plaintext, the line corresponding to the ECB ciphertext is changed, and the CBC ciphertext is changed from the line to the back.
5. RSA encryption (asymmetric encryption algorithm) (secret. frame system library)
Asymmetric encryption algorithms require two keys: public key (public key) and private key (private key)
The main algorithms used in asymmetric encryption are: RSA, Elgamal, knapsack algorithm, Rabin, D-H, ECC (elliptic curve cryptography algorithm), etc.
The public key and the private key are a pair, and if the public key is used for encrypting data, only the corresponding private key can be used for decrypting the data; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key.
The method is characterized in that:
the asymmetric cryptosystem has the characteristics that: the algorithm has complex strength and security depending on the algorithm and the secret key, but the algorithm is complex, so that the encryption and decryption speed is not as fast as the symmetric encryption and decryption speed
The symmetric cryptosystem has only one kind of key and is not public, and if the key is required to be decrypted, the opposite party can know the key. Therefore, the security of the key is ensured, and the asymmetric key body is provided with two keys, wherein one of the two keys is public, so that the key of the other party does not need to be transmitted like a symmetric cipher.
S203, the verification identification of the service server of the sending end is sent to the service server of the sending end.
S204, decrypting the verification identifier of the service server of the sending end according to a preset encryption mode identifier in the verification identifier of the service server of the sending end to obtain verification information of the service server of the sending end, wherein the verification information comprises a first mac address, a first user name and a first login password;
s205, comparing the verification information of the service server of the sending end with the login information;
and S206, if the verification information is the same as the login information, forwarding the request instruction to the service server of the receiving end.
