String

Methods

ComputeHMACSHA256(String, Byte[])

Computes a Hash-based Message Authentication Code (HMAC) by using the SHA256 hash function.

Declaration

public static string ComputeHMACSHA256(string value, byte[] secret)

Parameters

Type	Name	Description
String	value	The value to hash
Byte[]	secret	The secret key for HMACSHA256 encryption. The key can be any length. However, the recommended size is 64 bytes.

Returns

Type	Description
String	The hashed String.

ComputeHMACSHA384(String, Byte[])

Computes a Hash-based Message Authentication Code (HMAC) by using the SHA384 hash function.

Declaration

public static string ComputeHMACSHA384(string value, byte[] secret)

Parameters

Type	Name	Description
String	value	The value to hash
Byte[]	secret	The secret key for HMACSHA256 encryption. The key can be any length. However, the recommended size is 128 bytes.

Returns

Type	Description
String	The hashed String.

ComputeHMACSHA512(String, Byte[])

Computes a Hash-based Message Authentication Code (HMAC) by using the SHA512 hash function.

Declaration

public static string ComputeHMACSHA512(string value, byte[] secret)

Parameters

Type	Name	Description
String	value	The value to hash
Byte[]	secret	The secret key for HMACSHA256 encryption. The key can be any length. However, the recommended size is 128 bytes.

Returns

Type	Description
String	The hashed String.
