HashAlgorithmType Enum

SECURITY NOTE

Using weak or outdated hash algorithms (such as SHA-1) may allow threat actors to manipulate or predict hash values. Use modern, secure alternatives (such as SHA-256 or stronger).

Lists values used to specify the signature’s secure hash algorithm (SHA) type.

Public Enum HashAlgorithmType

Members

Name	Description
SHA1	SHA1 hashing algorithm. This type can affect the signature’s integrity, authenticity, and legal validity.
SHA256	SHA256 hashing algorithm.
SHA384	SHA384 hashing algorithm.
SHA512	SHA512 hashing algorithm.
