Class SymmetricCryptography

Service interface implementation for symmetrically encrypting/decrypting data (raw byte[] arrays) using System.Security.Cryptography.AesManaged.

Please keep in mind that the data you encrypt with EncryptWithPassword(byte[], string) can only be decrypted using the same password and the corresponding mirror method DecryptWithPassword(byte[], string).

Likewise, data encrypted using Encrypt(byte[]) can only be decrypted again using Decrypt(EncryptionResult) respectively. Implements the ISymmetricCryptography interface.

Returns

Type	Description
byte[]	Decrypted byte[] array or null if decryption failed.

DecryptAsync(EncryptionResult)

Asynchronously decrypts the specified EncryptionResult that was obtained using EncryptAsync(byte[]).

Declaration

public Task<byte[]> DecryptAsync(EncryptionResult encryptionResult)

Parameters

Type	Name	Description
EncryptionResult	encryptionResult	The EncryptionResult that was obtained using EncryptAsync(byte[]).
