Perhatian

Cryptographic factory methods accepting an algorithm name are obsolete. Use the parameterless Create factory method on the algorithm type instead.

Public Shared Function Create (hashName As String) As SHA1

Parameter

hashName

String

Nama implementasi spesifik yang SHA1 akan digunakan.

Mengembalikan

SHA1

Instans baru menggunakan SHA1 implementasi yang ditentukan.

Atribut

RequiresUnreferencedCodeAttribute ObsoleteAttribute

Keterangan

Karena masalah tabrakan dengan SHA-1, Microsoft merekomendasikan model keamanan berdasarkan SHA-256 atau lebih baik.
