Encrypt(Byte[], RSAEncryptionPadding)

When overridden in a derived class, encrypts the input data using the specified padding mode.
Encrypt(ReadOnlySpan<Byte>, RSAEncryptionPadding)

Encrypts the input data using the specified padding mode.
Encrypt(ReadOnlySpan<Byte>, Span<Byte>, RSAEncryptionPadding)

Encrypts the input data using the specified padding mode.

Public Overridable Function Encrypt (data As Byte(), padding As RSAEncryptionPadding) As Byte()
Public MustOverride Function Encrypt (data As Byte(), padding As RSAEncryptionPadding) As Byte()

Parameters

data
Byte[]

The data to encrypt.

padding
RSAEncryptionPadding

The padding mode.

Returns

Byte[]

The encrypted data.

Exceptions

ArgumentNullException

data or padding is null.

NotImplementedException

A derived class must override this method.

CryptographicException

padding is unknown, or not supported by this implementation.

-or-

The length of data is too long for the combination of KeySize and the selected padding.

-or-

The encryption operation failed.
