![]() The major drawback is that each decoded word can be encoded easily through any online tool and intruders can easily get the information. When you encode data in Base64, you start with a sequence of bytes and convert it to a text string.īase64 algorithm is usually used to store passwords in database. When you encode text in ASCII, you start with a text string and convert it to a sequence of bytes. 6 bits have a total of 64 combinations, so you need 64 characters to encode it. You can observe the following differences when you work on ASCII and base64 for encoding data − To interpret that as base64, you need to break it into groups of 6 bits. The code for base64 decoding gives you the following output − Difference between ASCII and base64 ![]() ![]() You can use the following piece of code to perform base64 decoding −ĭecoded_data = base64.b64decode("RW5jb2RlIHRoaXMgdGV4dA=") The code for base64 encoding gives you the following output − Program for Decoding You can use the following piece of code to perform base64 encoding −Įncoded_data = base64.b64encode("Encode this text") ![]() The binascii module contains low-level functions written in C for greater speed that are used by the higher-level modules. Normally, you will not use these functions directly but use wrapper modules like base64 instead. Python includes a module called BASE64 which includes two primary functions as given below −īcode(input, output) − It decodes the input value parameter specified and stores the decoded output as an object.īase64.encode(input, output) − It encodes the input value parameter specified and stores the decoded output as an object. The binascii module contains a number of methods to convert between binary and various ASCII-encoded binary representations. Base64 is also called as Privacy enhanced Electronic mail (PEM) and is primarily used in email encryption process. Decryption of Simple Substitution Cipherīase64 encoding converts the binary data into text format, which is passed through communication channel where a user can handle text safely.Before encoding or decoding, it is necessary to convert the strings from their native format (e.g. The `base64.b64encode()` function is used to encode a string into a Base64 string, while the `base64.b 64decode()` function is used to decode a Base 64string back into its original form. The `base64` module in Python provides functions for encoding and decoding strings using Base64. Therefore, we need to convert the string to bytes using `encode(‘utf-8’)` before encoding, and convert the bytes back to a string using `decode(‘utf-8’)` after decoding. To encode, we use `base64.b64encode()` while to decode we use `base64.b64decode()`.īoth encoding and decoding functions work with bytes-like objects. This script first encodes an original string into a Base64 string and then decodes the Base64 string back into the original string. # Decoding a Base64 string to original stringīase64_string = "RW5jb2RlIGFuZCBkZWNvZGUgc3RyaW5ncyBpbiBQeXRob24gdXNpbmcgQmFzZTY0"ĭecoded_bytes = base64.b64decode(base64_string.encode('utf-8'))ĭecoded_string = decoded_code('utf-8') Print("Encoded string:", encoded_code('utf-8')) Original_string = "Encode and decode strings in Python using Base64"Įncoded_string = base64.b64encode(original_string.encode('utf-8')) In Python, you can encode and decode a string using Base64 with the help of the `base64` module. This blog post will show you how to encode and decode strings using this module. In Python, the `base64` module provides functions for Base64 encoding and decoding. Base64 is a popular encoding format used to represent binary data in an ASCII string.
