> [!NOTE]
> If the Windows security policy setting for Federal Information Processing Standards (FIPS)-compliant algorithms is enabled, using this algorithm throws a <xref:System.Security.Cryptography.CryptographicException>.


> [!NOTE]
> Microsoft believes that it's no longer safe to decrypt data encrypted with the Cipher-Block-Chaining (CBC) mode of symmetric encryption (which is the default Mode for this class) when verifiable padding has been applied without first ensuring the integrity of the ciphertext, except for very specific circumstances. [Read more about timing vulnerabilities with CBC-mode symmetric decryption using padding.](/standard/security/vulnerabilities-cbc-mode)

## Examples
The following example demonstrates how to encrypt and decrypt sample data using the <xref:System.Security.Cryptography.AesManaged> class.
