Enum PaddingMode

Namespace

CryptoHives.Foundation.Security.Cryptography.Cipher

Assembly

CryptoHives.Foundation.Security.Cryptography.dll

Specifies the padding mode for block cipher operations.

[SuppressMessage("Design", "CA1008:Enums should have zero value", Justification = "Mirror runtime implementation")]
public enum PaddingMode

Fields

ANSIX923 = 4

ANSI X.923 padding. Pads with zeros, with the last byte indicating padding length.

ISO10126 = 5

ISO 10126 padding. Pads with random bytes, with the last byte indicating padding length.

None = 1

No padding. The plaintext must be an exact multiple of the block size.

PKCS7 = 2

PKCS#7 padding. Each padding byte contains the number of padding bytes added.

This is the most common padding mode and is compatible with PKCS#5. For a block size of 16 bytes, valid padding values are 0x01 through 0x10.

Zeros = 3

Zero padding. Pads with zero bytes.

Warning: Zero padding is ambiguous if the plaintext can end with zero bytes. Use PKCS#7 for unambiguous padding.

Remarks

Padding is required when the plaintext length is not a multiple of the block size. AEAD modes (GCM, CCM) and stream modes (CTR, Stream) do not require padding.

Values match PaddingMode for compatibility.
