Class: Defuse\Crypto\Key ========================= The `Key` class represents a secret key used for encrypting and decrypting. Once you have a `Key` instance, you can use it with the `Crypto` class to encrypt and decrypt strings and with the `File` class to encrypt and decrypt files. Instance Methods ----------------- ### saveToAsciiSafeString() **Description:** Saves the encryption key to a string of printable ASCII characters, which can be loaded again into a `Key` instance using `Key::loadFromAsciiSafeString()`. **Parameters:** This method does not take any parameters. **Return value:** Returns a string of printable ASCII characters representing this `Key` instance, which can be loaded back into an instance of `Key` using `Key::loadFromAsciiSafeString()`. **Exceptions:** - `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when the platform the code is running on cannot safely perform encryption for some reason (e.g. it lacks a secure random number generator), or the runtime tests detected a bug in this library. **Side-effects and performance:** None. **Cautions:** This method currently returns a hexadecimal string. You should not rely on this behavior. For example, it may be improved in the future to return a base64 string. Static Methods --------------- ### Key::createNewRandomKey() **Description:** Generates a new random key and returns an instance of `Key`. **Parameters:** This method does not take any parameters. **Return value:** Returns an instance of `Key` containing a randomly-generated encryption key. **Exceptions:** - `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when the platform the code is running on cannot safely perform encryption for some reason (e.g. it lacks a secure random number generator), or the runtime tests detected a bug in this library. **Side-effects and performance:** None. **Cautions:** None. ### Key::loadFromAsciiSafeString($saved\_key\_string, $do\_not\_trim = false) **Description:** Loads an instance of `Key` that was saved to a string by `saveToAsciiSafeString()`. By default, this function will call `Encoding::trimTrailingWhitespace()` to remove trailing CR, LF, NUL, TAB, and SPACE characters, which are commonly appended to files when working with text editors. **Parameters:** 1. `$saved_key_string` is the string returned from `saveToAsciiSafeString()` when the original `Key` instance was saved. 2. `$do_not_trim` should be set to `TRUE` if you do not wish for the library to automatically strip trailing whitespace from the string. **Return value:** Returns an instance of `Key` representing the same encryption key as the one that was represented by the `Key` instance that got saved into `$saved_key_string` by a call to `saveToAsciiSafeString()`. **Exceptions:** - `Defuse\Crypto\Exception\EnvironmentIsBrokenException` is thrown either when the platform the code is running on cannot safely perform encryption for some reason (e.g. it lacks a secure random number generator), or the runtime tests detected a bug in this library. - `Defuse\Crypto\Exception\BadFormatException` is thrown whenever `$saved_key_string` does not represent a valid `Key` instance. **Side-effects and performance:** None. **Cautions:** None.
