Quantum Readiness

Categories:

Post-Quantum Cryptography: NIST-approved PQC (Kyber, Dilithium, SPHINCS+)
Quantum-Safe Classical: Symmetric/hash with 256+ bit security (AES-256, SHA-256)
Quantum-Resistant Uncertain: Needs validation (AES-128, XMSS, some hash functions)
Quantum-Vulnerable: Broken by Shor's algorithm (RSA, ECDSA, DH)
Classically Weak: Broken TODAY (MD5, SHA-1, DES, RC4)
Unknown: Generic names, unidentifiable algorithms

By Algorithm Type

Algorithm Types:

Block Cipher: Symmetric encryption (AES, DES, ChaCha20)
Hash Function: One-way digest (SHA-256, MD5, BLAKE2)
Digital Signature: Asymmetric signing (RSA, ECDSA, Dilithium)
Message Authentication: MAC codes (HMAC, CMAC, Poly1305)
Key Derivation: KDF functions (PBKDF2, Argon2, HKDF)
Public Key Encryption: Asymmetric encryption (RSA, Kyber)
Public Key Cipher: Public key cryptography (RSA, ElGamal)
Key Exchange: Key agreement (ECDH, X25519, Kyber-KEM)
Authenticated Encryption: Combined encryption+MAC (AES-GCM, ChaCha20-Poly1305)
Extendable-Output Function: Variable-length output (SHAKE128, SHAKE256)
Other: Miscellaneous or unclassified algorithms

By Purpose

Purpose Types:

Encryption: Protect data confidentiality
Decryption: Recover original data
Digital Signing: Prove authenticity and integrity
Signature Verification: Validate digital signatures
Key Generation: Create cryptographic keys
Key Agreement: Establish shared secrets
Hashing: Generate message digests
Other: Miscellaneous or unclassified operations

Shorstop reports automated source-code findings for investigation. Matches can include example code, commented-out code and non-production usage, and should be reviewed in context. Test directories, vendored dependencies and build output are not scanned. A Shorstop scan is not a substitute for a formal security assessment. How scanning worksFound an incorrect result? Report it.
