## EncryptionAlgorithms\.ContentEncryption Class

Content encryption algorithms \("enc" parameter in the JWE header\)\. These encrypt the
JWE payload using the Content Encryption Key produced by the key management algorithm\.

```csharp
public static class EncryptionAlgorithms.ContentEncryption
```

### Fields

## EncryptionAlgorithms\.ContentEncryption\.Aes128CbcHmacSha256 Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes128CbcHmacSha256}

AES\-128\-CBC with HMAC\-SHA\-256 authentication \(RFC 7518 Section 5\.2\)\. Backed by \.NET
`Aes` in CBC/PKCS7 mode and `HMACSHA256`; the 256\-bit CEK is split into a
128\-bit MAC key and a 128\-bit AES key\.

```csharp
public const string Aes128CbcHmacSha256 = "A128CBC-HS256";
```

#### Field Value
[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')

## EncryptionAlgorithms\.ContentEncryption\.Aes128Gcm Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes128Gcm}

AES\-128 in Galois/Counter Mode \(RFC 7518 Section 5\.3\)\. Backed by \.NET `AesGcm`
with a 96\-bit IV and 128\-bit authentication tag\. Single\-pass authenticated encryption\.

```csharp
public const string Aes128Gcm = "A128GCM";
```

#### Field Value
[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')

## EncryptionAlgorithms\.ContentEncryption\.Aes192CbcHmacSha384 Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes192CbcHmacSha384}

AES\-192\-CBC with HMAC\-SHA\-384 authentication \(RFC 7518 Section 5\.2\)\. Backed by \.NET
`Aes` in CBC/PKCS7 mode and `HMACSHA384`; uses a 384\-bit CEK\.

```csharp
public const string Aes192CbcHmacSha384 = "A192CBC-HS384";
```

#### Field Value
[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')

## EncryptionAlgorithms\.ContentEncryption\.Aes192Gcm Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes192Gcm}

AES\-192 in Galois/Counter Mode \(RFC 7518 Section 5\.3\)\. Backed by \.NET `AesGcm`
with a 96\-bit IV and 128\-bit authentication tag\.

```csharp
public const string Aes192Gcm = "A192GCM";
```

#### Field Value
[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')

## EncryptionAlgorithms\.ContentEncryption\.Aes256CbcHmacSha512 Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes256CbcHmacSha512}

AES\-256\-CBC with HMAC\-SHA\-512 authentication \(RFC 7518 Section 5\.2\)\. Backed by \.NET
`Aes` in CBC/PKCS7 mode and `HMACSHA512`; uses a 512\-bit CEK\.
Default content encryption used by this library when issuing encrypted tokens\.

```csharp
public const string Aes256CbcHmacSha512 = "A256CBC-HS512";
```

#### Field Value
[System\.String](https://learn.microsoft.com/en-us/dotnet/api/system.string 'System\.String')

## EncryptionAlgorithms\.ContentEncryption\.Aes256Gcm Field {#Abblix.Jwt.EncryptionAlgorithms.ContentEncryption.Aes256Gcm}

AES\-256 in Galois/Counter Mode \(RFC 7518 Section 5\.3\)\. Backed by \.NET `AesGcm`
with a 96\-bit IV and 128\-bit authentication tag\. Recommended where peers support GCM\.

```csharp
public const string Aes256Gcm = "A256GCM";
```
