cryptoscan is a bash script to check system binaries (like executables or shared libraries) for embedded statically linked crypto implementations.
Currently it can detect AES, BLOWFISH,ChaCha20, Curve25519, DES, MD5, RIPEMD, SHA, SIPHASH, WHIRLPOOL by searching the binaries for well-known constants used within the respective algorithms.
$ ./cryptoscan /bin
