Solutions to cryptest: command not found

How To Fix cryptest: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu cryptest is provided by libcrypto++-utils package.

libcrypto++-utils is:

Crypto++ is library for creating C++ programs which use cryptographic algorithms. The library uses a Pipes & Filters architecture with heavy use of templates and abstract base classes. The cryptographic tools include:

  • Authenticated encryption schemes (GCM, CCM, EAX),
  • High speed stream ciphers (Panama, Sosemanuk, Salsa20, XSalsa20),
  • AES and candidates (Rijndael, RC6, MARS, Twofish, Serpent, CAST-256),
  • Other symmetric block ciphers (IDEA, Triple-DES, Camellia, SEED, RC5, Blowfish, TEA, XTEA, Skipjack, SHACAL-2),
  • Block cipher modes of operation (ECB, CBC, CTS, CFB, OFB, CTR),
  • Message authentication codes (VMAC, HMAC, CMAC, CBC-MAC, DMAC, Two-Track-MAC),
  • Hash functions (SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, Tiger, WHIRLPOOL, RIPEMD-128, RIPEMD-256, RIPEMD-160, RIPEMD-320),
  • Public-key cryptography (RSA, DSA, ElGamal, NR, RW, LUC, LUCELG, DLIES, ESIGN),
  • Padding schemes for public-key systems (PKCS#1, OAEP, PSS, PSSR, EMSA2, EMSA5),
  • Key agreement schemes (DH, MQV, LUCDIF, XTR-DH),
  • Elliptic curve cryptography (ECDSA, ECNR, ECIES, ECDH, ECMQV),
  • Backwards compatibility algorithms (MD2, MD4, MD5, Panama Hash, DES, ARC4, SEAL 3.0, WAKE, WAKE-OFB, DESX, RC2, SAFER, 3-WAY, GOST, SHARK, CAST-128, Square),
  • Pseudo-random number generators, and a whole lot more. Alternative libraries are libgcrypt and nettle.

This package includes a utility for benchmarking and using the various Crypto++ routines from the command line. It also includes the test vectors for validating both the Crypto++ implementation and other implementations of these routines.

To fix this problem, we can install more using the command below.

sudo apt-get -y install libcrypto++-utils

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install libcrypto++-utils.

sudo apt -y install libcrypto++-utils

Or if you have aptitude installed you can use the following command.

sudo aptitude install libcrypto++-utils
