Fast cryptographic functions (SHA-256, MD5, HMAC, Base64/32, CRC32) powered by BMB

bmb-crypto — Fast Cryptographic Functions

Standards-compliant hashing, encoding, and checksums compiled from BMB.

Installation

pip install bmb-crypto

Quick Start

import bmb_crypto

bmb_crypto.sha256("hello")
# '2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824'

bmb_crypto.md5("hello")
# '5d41402abc4b2a76b9719d911017c592'

bmb_crypto.hmac_sha256("key", "message")
# RFC 2104 compliant HMAC-SHA256

bmb_crypto.base64_encode("hello")   # 'aGVsbG8='
bmb_crypto.base64_decode("aGVsbG8=")  # 'hello'

bmb_crypto.crc32("hello")           # '3610a686'
bmb_crypto.adler32("Wikipedia")     # '11e60398'

Full API (14 functions)

Function	Standard	Output
sha256(data)	FIPS 180-4	64-char hex
md5(data)	RFC 1321	32-char hex
crc32(data)	ISO 3309	8-char hex
hmac_sha256(key, msg)	RFC 2104	64-char hex
base64_encode(data)	RFC 4648	Base64 string
base64_decode(data)	RFC 4648	Original string
base32_encode(data)	RFC 4648	Base32 string
base32_decode(data)	RFC 4648	Original string
adler32(data)	RFC 1950	8-char hex
fletcher16(data)	Fletcher-16	4-char hex
xor_checksum(data)	XOR	2-char hex
rot13(data)	ROT13	Transformed string
hex_encode(data)	Hex	Hex string
hex_decode(data)	Hex	Original string

All outputs cross-validated against Python's hashlib, binascii, hmac, and base64.

How?

Written in BMB — compile-time contracts prove correctness, then generate code faster than hand-tuned C.
