Crypto algorithms and encryption technology

Choosing a blockchain system design may be guided by crypto library and encryption technology as well. An organization's use case requirements will dictate this choice and drive technology investments in blockchain application infrastructure:

Asymmetric: RSA (1024-8192), DSA (1024-3072), Diffie-Hellman, KCDSA, Elliptic Curve Cryptography (ECDSA, ECDH, ECIES) with named, user-defined, and brainpool curves
Symmetric: AES, RC2, RC4, RC5, CAST, DES, Triple DES, ARIA, SEED
Hash/message digest/HMAC: SHA-1, SHA-2 (224-512), SSL3-MD5-MAC, SSL3-SHA-1-MAC, SM3
Random number generation: FIPS 140-2 approved DRBG (SP 800-90 CTR mode)
