klyn.cryptography.MessageDigest.getInstance
method
public static getInstance(algorithm as String) as MessageDigest throws CryptoException:
Description
Compatibility factory for dynamic algorithm selection. Direct subclass construction such as `SHA256()` or `SHA3_512()` remains the primary API. This helper exists for configuration-driven code paths and for transition from the previous design. 
import klyn.cryptography

name = "SHA-256"
md = MessageDigest.getInstance(name)
print(md.algorithm)
Parameters
  • algorithm Digest algorithm.
Returns
Ready-to-use digest instance.
Throws
  • CryptoException when the algorithm is unsupported. ```klyn import klyn.cryptography name = "SHA-256" md = MessageDigest.getInstance(name) print(md.algorithm) ```
