First, Base64 coding principle Step 1: Convert all characters to ASCII code; Step 2: Convert the ASCII code into a 8-bit binary; Step 3: The binary 3 grouped into a group (less than 3 in the back of 0) a total of 24, and then split into 4 groups,

I. Base64 encoding Principle Step 1: Convert all characters into ASCII codes;Step 2: Convert the ASCII code into an 8-bit binary code;Step 3: Combine the binary three into a group (less than three are supplemented with 0) with a total of 24 bits

I. Brief description MD5: All called message digest algorithm 5 (Information digest algorithm), can be encrypted, but not decrypted, belong to one-way encryption, usually used for file verification BASE64: The 8-bit byte of any sequence is

The following is a detailed description of how BASE64 is encoded.The so-called Base64, that is to choose 64 characters----lowercase letter A-Z, uppercase letter A-Z, number 0-9, the symbol "+", "/" (plus the "=" as the pad word, is actually 65

One:. Base64 Supplement"' OBJC1.base64 Simple ExplanationDescription: Base64 can be a cornerstone of cryptography and is very important.Features: Arbitrary binary data can be BASE64 encodedResult: All data can be encoded as a text file that can be

I. Introduction to the Concept Base64 is a representation of binary data based on 64 printable characters. Because of 2^6=64, every 6 bits is a unit, corresponding to a printable character. 3 bytes have 24 bits, corresponding to 4 Base64 units, 3
