class System.Security.Cryptography.ChaCha20Poly1305
Assembly: System.Security.Cryptography
Inheritance: object → ChaCha20Poly1305
Implemented Interfaces
Represents a symmetric key to be used with the ChaCha20 stream cipher in the combined mode with the Poly1305 authenticator.
Properties
public static
bool
IsSupported
Gets a value that indicates whether the algorithm is supported on the current platform.
Methods
public
void
Decrypt(byte[] nonce,
byte[] ciphertext,
byte[] tag,
byte[] plaintext,
byte[] associatedData = null)
Decrypts the ciphertext into the provided destination buffer if the authentication tag can be validated.
nonce
The nonce associated with this message, which must match the value provided during encryption.
ciphertext
The encrypted content to decrypt.
tag
The authentication tag produced for this message during encryption.
plaintext
The byte array to receive the decrypted contents.
associatedData
Extra data associated with this message, which must match the value provided during encryption.
public
void
Decrypt(ReadOnlySpan<byte> nonce,
ReadOnlySpan<byte> ciphertext,
ReadOnlySpan<byte> tag,
Span<byte> plaintext,
ReadOnlySpan<byte> associatedData = null)
Decrypts the ciphertext into the provided destination buffer if the authentication tag can be validated.
nonce
The nonce associated with this message, which must match the value provided during encryption.
ciphertext
The encrypted content to decrypt.
tag
The authentication tag produced for this message during encryption.
plaintext
The byte array to receive the decrypted contents.
associatedData
Extra data associated with this message, which must match the value provided during encryption.
public
void
Dispose()
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
public
void
Encrypt(byte[] nonce,
byte[] plaintext,
byte[] ciphertext,
byte[] tag,
byte[] associatedData = null)
Encrypts the plaintext into the ciphertext destination buffer and generates the authentication tag into a separate buffer.
nonce
The nonce associated with this message, which should be a unique value for every operation with the same key.
plaintext
The content to encrypt.
ciphertext
The byte array to receive the encrypted contents.
tag
The byte array to receive the generated authentication tag.
associatedData
Extra data associated with this message, which must also be provided during decryption.
public
void
Encrypt(ReadOnlySpan<byte> nonce,
ReadOnlySpan<byte> plaintext,
Span<byte> ciphertext,
Span<byte> tag,

Encrypts the plaintext into the ciphertext destination buffer and generates the authentication tag into a separate buffer.
nonce
The nonce associated with this message, which should be a unique value for every operation with the same key.
plaintext
The content to encrypt.
ciphertext
The byte array to receive the encrypted contents.
tag
The byte array to receive the generated authentication tag.
associatedData
Extra data associated with this message, which must also be provided during decryption.
