Intel® Integrated Performance Primitives Cryptography (Intel® IPP Cryptography) is a secure, fast and lightweight library of building blocks for cryptography, highly-optimized for various Intel® CPUs.

The library provides a comprehensive set of routines commonly used for cryptographic operations, including:

• Symmetric Cryptography Primitive Functions:
  • AES (ECB, CBC, CTR, OFB, CFB, XTS, GCM, CCM, SIV)
  • SM4 (ECB, CBC, CTR, OFB, CFB, CCM)
  • TDES (ECB, CBC, CTR, OFB, CFB)
  • RC4
• One-Way Hash Primitives:
  • SHA-1, SHA-224, SHA-256, SHA-384, SHA-512
  • MD5
  • SM3
• Data Authentication Primitive Functions:
  • HMAC
  • AES-CMAC
• Public Key Cryptography Functions:
  • RSA, RSA-OAEP, RSA-PKCS_v15, RSA-PSS
  • DLP, DLP-DSA, DLP-DH
  • ECC (NIST curves), ECDSA, ECDH, EC-SM2
• Multi-buffer RSA, ECDSA, ECDH, x25519, SM2, SM3, SM4, etc
• Finite Field Arithmetic Functions
• Big Number Integer Arithmetic Functions
• PRNG/TRNG and Prime Numbers Generation

• Security (constant-time execution for secret processing functions)
• Designed for the small footprint size
• Optimized for different Intel CPUs and instruction set architectures (including hardware cryptography instructions support):
  • Intel® Streaming SIMD Extensions 2 (Intel® SSE2)
  • Intel® SSE3
  • Intel® SSE4.2
  • Intel® Advanced Vector Extensions (Intel® AVX)
  • Intel® Advanced Vector Extensions 2 (Intel® AVX2)
  • Intel® Advanced Vector Extensions 512 (Intel® AVX-512)
• Configurable CPU dispatching for the best performance
• Kernel mode compatibility
• Thread-safe design

Intel IPP Cryptography supports building blocks (self-tests, services) for FIPS 140-3 compliance. See [FIPS] (./README_FIPS.md) document for details.
