Caution
AesGcm should indicate the required tag size for encryption and decryption. Use a constructor that accepts the tag size.

Exceptions
The key parameter is null.
The key parameter length is other than 16, 24, or 32 bytes (128, 192, or 256 bits).

new System.Security.Cryptography.AesGcm : ReadOnlySpan<byte> -> System.Security.Cryptography.AesGcmPublic Sub New (key As ReadOnlySpan(Of Byte))Parameters
- key
- ReadOnlySpan<Byte>
The secret key to use for this instance.
- Attributes
Exceptions
The key parameter length is other than 16, 24, or 32 bytes (128, 192, or 256 bits).
Applies to
AesGcm(Byte[], Int32)
- Source:
- AesGcm.cs
- Source:
- AesGcm.cs
Initializes a new instance of the AesGcm class with a provided key and required tag size.
public:
AesGcm(cli::array <System::Byte> ^ key, int tagSizeInBytes);public AesGcm (byte[] key, int tagSizeInBytes);new System.Security.Cryptography.AesGcm : byte[] * int -> System.Security.Cryptography.AesGcmPublic Sub New (key As Byte(), tagSizeInBytes As Integer)Parameters
- key
- Byte[]
The secret key to use for this instance.
- tagSizeInBytes
- Int32
The size of the tag, in bytes, that encryption and decryption must use.
Exceptions
The key parameter is null.
The key parameter length is other than 16, 24, or 32 bytes (128, 192, or 256 bits).
The tagSizeInBytes parameter is an unsupported tag size indicated by
TagByteSizes.
The current platform does not support AES-GCM.
Remarks
The tagSizeInBytes parameter is used to indicate that the tag parameter in Encrypt or Decrypt must be exactly this size. Indicating the required tag size prevents issues where callers of Decrypt may supply a tag as input and that input is truncated to an unexpected size.
