							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 *
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * - Encryption/decryption: [[encrypt()]] and [[decrypt()]]
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * - Data tampering prevention: [[hashData()]] and [[validateData()]]
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * - Password validation: [[generatePasswordHash()]] and [[validatePassword()]]
							 |

							 | 
							
							
								 *
							 |

							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * Additionally, Security provides [[getSecretKey()]] to support generating
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * named secret keys. These secret keys, once generated, will be stored in a file
							 | 
						
					
						
							| 
								
							 | 
							
								
							 | 
							
								
							 | 
							
							
								 * and made available in future requests.
