Simplified functions for nodejs cryptography.
#### cryptography.encrypt(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
* options.callback
* error
* encrypted
Returns a promise which is resolved with encrypted string. If a callback is passed it is called with encrypted string.
#### cryptography.encryptSync(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
Synchronous encrypt(). Returns encrypted string.
#### cryptography.decrypt(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
* options.callback
* error
* decrypted
Returns a promise which is resolved with decrypted string. If a callback is passed it is called with decrypted string.
#### cryptography.decryptSync(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
Synchronous decrypt(). Returns decrypted string.
#### cryptography.hmac(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
* options.callback
* error
* hashed
Returns a promise which is resolved with hashed string. If a callback is passed it is called with hashed string.
#### cryptography.hmacSync(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
Synchronous hmac(). Returns hashed string.
#### cryptography.hash(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
* options.callback
* error
* hashed
Returns a promise which is resolved with hashed string. If a callback is passed it is called with hashed string.
#### cryptography.hashSync(options)
* options |
* options.key
* options.algorithm
* options.encoding
* options.data
Synchronous hash(). Returns hashed string.
#### cryptography.randomBytes(options)
* options |
* options.size
* options.encoding
* options.callback
* error
* randomBytes
Returns a promise which is resolved with random bytes string. If a callback is passed it is called with random bytes string.
#### cryptography.randomBytesSync(options)
* options |
* options.size
* options.encoding
Synchronous randomBytes(). Returns random bytes string.
