Fields

TokenCommand

The command used by image requests for transporting Hash-based Message Authentication Code (HMAC) tokens.

Declaration

public const string TokenCommand = "hmac"

Field Value

Type	Description
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.
