![]() Other Base64 variations share the same property but they use different symbols in the last two values. The Base64 implementation in MIME uses a-z, A-Z and 0-9 for the first 62 values. This mixture leaves the data impossible to be altered in transportation thru information systems, such as electronic mail, that were typically not 8-bit clean. The common concept is to select a set of 64 characters that is both part of a subset typical to most encodings. The specific set of characters chosen for the 64 characters needed for the base can vary among implementations. Base64 is generally used in a number of applications including electronic mail via MIME, and keeping complex information in XML. This guarantees that the data stays unchanged without modification during transfer. s contains a byte-like object that is to be encoded. Prototype and parameters The base64.b64encode () function takes s as a non-optional parameter and altchars as an optional parameter. Types of URI charactersīase64 encoding schemes are generally used when there is a need to encode binary information that needs to be stored and transferred over media that are developed to deal with textual information. The base64.b64 () function in Python encodes byte-like objects and returns the encoded bytes. Basically, Base64 is a collection of related encoding designs which represent the binary information in ASCII format by converting it into a base64 representation. To Base64 encode these bytes, we use the base64.b64encode () function: import base64 s 'Hello World' b s.encode('UTF-8') e base64.b64encode(b) print(e) That code would output the following: b'SGVsbG8gV29ybGQh' which is still in the bytes object. To decode Base64 data in Python, you can use the base64 module to access the necessary functions. In Python, base64 module provides efficient and easy-to-use. The quoted-printable encoding is designed for data where there are relatively few nonprintable characters the base64 encoding scheme available via the base64 module is more compact if there are many such characters, as when sending a graphics file. The term Base64 is coming from a certain MIME content transfer encoding. Base64 is a common encoding technique used to convert binary data into ASCII text format. ![]() encode ( 'utf-8' ) # Next, use the base64 decode method to decode the bytes to base64īase64_bytes = base64. My_string = 'SGVsbG8gV29ybGQ=' # First, transform the string into its respective bytes This article contains examples that demonstrate. Just be sure not to mix up strings with byte strings! import base64 Pythons base64 module provides functions to perform Base64 encoding and decoding as described in RFC 3548. b64encode (my_bytes ) ) print (base64_string ) Decoding a String using Base64 in Pythonĭecoding a base64 string works similar to encoding. You can also take this a step further and eliminate the need to encode the string to bytes by prepending the string with a byte indicator like so: my_bytes = b'Hello World'īase64_string = str (base64. b64encode (my_bytes ) # Finally, you can convert the bytes to a string again if needed:īase64_string = str (base64_bytes ) print (base64_string ) encode ( 'utf-8' ) # Next, use the base64 encode method to encode the bytes to base64īase64_bytes = base64. # This can be set as ascii, uti-8, utf-16, utf-32 My_string = 'Hello World' # First, encode the string into its respective bytes using the encode method. # This is the string you want to encode to base64 You can base64 encode a string in Python by first converting it into its appropriate bytes and then using the b64encode method: import base64 To solve this, make sure you are handling the casting correctly, summarized below. The drawback of base64 encoding is that it renders the text non-human readable. This is a good encoding to use when most of your payload is unprintable data since it is a more compact form than quoted-printable. ![]() This is a common issue and originates from when Python changed some of its string mechanics from version 2 to 3. Encodes the payload into base64 form and sets the Content-Transfer-Encoding header to base64. First, the strings are converted into byte-like objects and then encoded using the base64 module. This error occurs when you try to base64 encode or decode a string instead of an appropriate bytes-like object. In Python the base64 module is used to encode and decode data. TypeError: a bytes-like object is required, not 'str'
