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

| 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
