![]() ![]() People commonly encounter when trying to work with Unicode. base64.b64decode(encoded_data, altchars=None): Decodes the encoded data using the specified alternative characters, if provided.ĭata = "UHl0aG9uIGlzIGEgcHJvZ3JhbW1pbmcgbGFuZ3VhZ2U="īase64_string = base64_bytes.This HOWTO discusses Python’s support for the Unicode specificationįor representing textual data, and explains various problems that base64.b64decode(encoded_data.encode()): Decodes the encoded data (as a string) and returns the decoded data as a bytes object.ģ. base64.b64decode(encoded_data`: Decodes the Base64-encoded `encoded_data` (bytes-like object) and returns the decoded data as a bytes object.Ģ. The `base64` library provides functions to decode Base64-encoded data:ġ. Print "encoded message:", repr(open("out.b64").read())Įncoded message: 'bGlmZSBvZiBicmlhbg=\012' String = ‘Python is a programming language’Įncode_data: UHl0aG9uIGlzIGEgcHJvZ3JhbW1pbmcgbGFuZ3VhZ2U=īase64.encode(open("python.txt"), open("python.b64", "w")) We must import 'encodestring' from the base64 library in order to use this method. `base64.b64encode(data, altchars=None)`: Encodes the data using the specified alternative characters, if provided.ĭata = "Python is a programming language"īase64_bytes = base64.b64encode(data_bytes)ĮncodedData: UHl0aG9uIGlzIGEgcHJvZ3JhbW1pbmcgbGFuZ3VhZ2U=īase64.encodestring() This technique allows us to directly encode the string. `base64.b64encode(data).decode()`: Encodes the data and returns the encoded data as a string (Unicode).ģ. `base64.b64encode(data)`: Encodes the given `data` (bytes-like object) and returns the encoded data as a bytes object.Ģ. The `base64` library provides several functions to encode data:ġ. * Align the corresponding Base64 values for each decimal number using the Base64 encoding table.Īn illustration of a Base64 encoding table is shown below. ![]() * Convert the 6-bit binary groups to their respective decimal values. * By reorganising the digits, divide the 8-bit character chunk into 6 bit pieces. * Compute the 8-bit binary equivalent of the ASCII values * Get the ASCII value of each character in the string. The procedures listed below must be taken in order to convert a string into a Base64 character: Six bits of data are represented by each Base64 character. * Abcdefghijklmnopqrstuvwxyz (26 lowercase letters)Īdditionally, the data stream is padded at the end with the = character. * ABCDEFGHIJKLMNOPQRSTUVWXYZ (26 uppercase letters) Base64 encoding:Įach group of three bytes is stored as a group of four characters from the following set to encode data: * Base85: This encoding uses eight ASCII characters to represent each four bytes of data. * Ascii85: This encoding uses eight ASCII characters to represent each three bytes of data. * Base64: This encoding uses four ASCII characters to represent each byte of data. * Base32: This encoding uses five ASCII digits to represent each byte of data. * Base16: This encoding uses two hexadecimal digits to represent each byte of data. * b64decode(): This function decodes an ASCII bytes object to bytes using the specified encoding * b64encode(): This function encodes a bytes-like object to ASCII bytes using the specified encoding. After importing the module, you can encode and decode data using the following functions: You must first import the base64 module into your Python programme before you can use it. Compared to the legacy interface, it is more adaptable and effective. * The legacy interface: It offers operations for encoding and decoding to and from file objects but does not provide decoding from strings.įor the majority of apps, the modern interface is recommended. * The modern interface: This interface allows you to encode things that resemble bytes in ASCII bytes and decode items that resemble bytes or strings that contain ASCII in bytes. ![]() The base64 module provides two interfaces for encoding and decoding binary data: This enables the secure transmission of binary data via protocols like email and HTTP that only handle ASCII characters. A common encoding method called Base64 converts binary data into a string of printable ASCII characters. ![]() A built-in module in Python, the base64 library offers functions for encoding and decoding binary data to and from base64 strings, effectively converting any binary data to plain text. ![]()
