Base64 is one of the most common encoding methods used to transmit 8-bit code on the network. When sending an email, the user name and password for server authentication must be base64 encoded, the attachment must also be base64-encoded. The

Generate a short token string Sometimes, we need to generate some tokens as the identifiers, such as the authenticated identifiers and resource extraction codes. A common algorithm is to generate a guid as the token. Because of its randomness and

BASE64 encoding is the process of binary to character.BASE64 encoding is mainly used in the fields of transmission, storage, binary, etc., and can be used for encryption, but this kind of encryption is relatively simple.byte[] ByteArray =

Developers are sure to be familiar with Base64 coding, and whether or not they have a clear understanding of it is not necessarily. In fact, Base64 is simply no longer easy, and if it's understood or ambiguous, it shouldn't be. About Base64, take a

Digest Algorithm (HASHLIB)Python's hashlib provides a common digest algorithm, such as MD5,SHA1 and so on.What is a digest algorithm? Abstract the algorithm is also called hash algorithm and hashing algorithm. It converts any length of data into a

PHP support for Base64 is very good, there is a built-in Base64_encode and Base64_decode responsible for the image of the Base64 encoding and decoding.On the encoding, as long as the picture stream is read, and then using Base64_encode to encode can

Coding I. Coding rulesThe idea of BASE64 encoding is to encode the data using 64 basic ASCII characters. It splits the data that needs to be encoded into a byte array. A group of 3 bytes. Arrange the 24-bit data in order, then divide the 24-bit data

Overview: For security reasons, transport data is often encrypted and encoded in the transmission of the network, which involves the following: 1, MD5 encryption, the encryption algorithm is one-way encryption, that is, the encrypted data can no

Brief introduction Base64 is a representation that represents binary data based on 64 printable characters. Because 2 of the 6 times equals 64, each 6 bit is a unit, corresponding to a printable character. Three bytes have 24 bits, corresponding to

In general, the parameters in the URL should use the URL encoding rules, that is, the parameter string in addition to-_. All non-alphanumeric characters are replaced with a percent sign (%) followed by a two-bit hexadecimal number, and the space is
