+# Encrypter
+
+This is a small library used to encrypt passwords.
+
+
+
+`com.lobosstudios.crypter.Encrypter.encrypt(String unencrypted, String ourSalt)` generates a hash using SHA-512. The encrypted password is prefixed with the string `{CRYPT}` (for historical reasons that probably won't make sense to anyone except me; I lifted the code from a small library I wrote years ago).
+
+If you are generating a hash from a plaintext password, `ourSalt` must be null. The salt is only specified when you are verifying a password.
+
+`com.lobosstudios.crypter.Encrypter. verify(String encrypted, String passwordToVerify)` returns true if the encrypted hash matches the unencrypted password. The passwords are compared this way:
+* The salt is extract from the encrypted password.
+* `encrypt()` is called, passing the plaintext password and the salt.
+* Given the same salt and the same plaintext password, `encrypt()` will return the same string we passed in. If the string we generate is identical to `encrypted`, we return true; otherwise we return false.
+
+## CLI
+
+`java -jar crypter-VERSION-all.jar [ -v | --verify]`
+
+Allows you to generate a password, and copies the encrypted password to the clipboard, unless `-v` or `--verify` is specified, in which case you are prompted
+for the encrypted password, then you are prompted for a plaintext password, and the two are compared; you are told either that they match, or they don't match.
+
+If `-v` or `--verify` is specified, the option must come AFTER `-jar`.
+
+## Dependencies
+
+Crypter's only dependency is on the Apache Commons Codec library.
+
+## Maven Coordinates
+
+Crypter is hosted in Lobos Studios' `java-dev` repository.
+
+To use the repo with Gradle:
+
+```groovy
+repositories {
+ mavenCentral()
+ maven {
+ url "https://repos.lobosstudios.com/repository/java-dev/"
+ }
+}
+
+dependencies {
+ implementation "com.lobosstudios:crypter:[VERSION]"
+}
+```
+
+To use it with Maven:
+
+```xml
+
+
+ lobosstudios-nexus-java-dev
+ Lobos Studios java-dev
+ https://repos.lobosstudios.com/repository/java-dev/
+
+
+
+
+
+ com.lobosstudios
+ crypter
+ [VERSION]
+
+
+```
+
+***repos.lobosstudios.com is hosted on a Sonatype Nexus server. Repos hosted on Nexus require the slash at the end of the URL. Don't forget it!***
