Constructors

ChaCha20Poly1305(Byte[])

Initializes a new instance of the ChaCha20Poly1305 class with a provided key.
ChaCha20Poly1305(ReadOnlySpan<Byte>)

Initializes a new instance of the ChaCha20Poly1305 class with a provided key.

Properties

IsSupported

Gets a value that indicates whether the algorithm is supported on the current platform.

Methods

Decrypt(Byte[], Byte[], Byte[], Byte[], Byte[])

Decrypts the ciphertext into the provided destination buffer if the authentication tag can be validated.
Decrypt(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, Span<Byte>, ReadOnlySpan<Byte>)

Decrypts the ciphertext into the provided destination buffer if the authentication tag can be validated.
Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Encrypt(Byte[], Byte[], Byte[], Byte[], Byte[])

Encrypts the plaintext into the ciphertext destination buffer and generates the authentication tag into a separate buffer.
Encrypt(ReadOnlySpan<Byte>, ReadOnlySpan<Byte>, Span<Byte>, Span<Byte>, ReadOnlySpan<Byte>)

Encrypts the plaintext into the ciphertext destination buffer and generates the authentication tag into a separate buffer.
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
ToString()

Returns a string that represents the current object.
