Python Binascii Module
Binary data conversions — hexlify, unhexlify, crc32, base64. This category documents 5 Python binascii module entries, and each page gives you the full syntax, the parameter list, the return value, and a runnable example. The entries include: binascii.hexlify(), binascii.unhexlify(), binascii.crc32(), binascii.a2b_base64(), binascii.b2a_base64(). binascii.hexlify() converts bytes to hexadecimal representation (like bytes.hex()). binascii.unhexlify() converts hexadecimal representation back to bytes. binascii.crc32() computes CRC-32 checksum of data (for error detection, not security). binascii.a2b_base64() converts base64 ASCII string to bytes (alternative to base64.b64decode). binascii.b2a_base64() converts bytes to base64 ASCII string. Binascii Module belongs to the File & Data group alongside Pathlib Module, Shutil Module, Glob Module, Fileinput Module. You can also search across every category from the search page, browse the complete A–Z index, or try any example in the Python playground. Python Reference documents 978+ functions, methods, and modules across 114 categories of the standard library, and every entry in this Binascii Module category follows the same format — syntax first, then what it does, the parameters it accepts, what it returns, and a working code example — so once you have read one page you can read them all.
