Summary

The return object (Signature) of Get-AuthenticodeSignature cmdlet now includes a new SubjectAlternativeName property (added in PowerShell/PowerShell#26252) that exposes the Subject Alternative Name extension from the signer certificate as a string[] array.

Ket points to document:

• Property type: string[]
• Returns null when certificate has no SAN extension
• Each array element contains one SAN entry (e.g., "DNS Name=example.com", "RFC822 Name=email@example.com")
• Useful for security validation and certificate trust decisions
