# PGPainless-SOP [](https://datatracker.ietf.org/doc/html/draft-dkg-openpgp-stateless-cli-03) [](https://search.maven.org/artifact/org.pgpainless/pgpainless-sop) [](https://pgpainless.org/releases/latest/javadoc/org/pgpainless/sop/package-summary.html) [](https://api.reuse.software/info/github.com/pgpainless/pgpainless) Implementation of the Stateless OpenPGP Protocol using PGPainless. This module implements `sop-java` using `pgpainless-core`. If your code depends on `sop-java`, this module can be used as a realization of those interfaces. ## Usage Examples ```java SOP sop = new SOPImpl(); // Generate an OpenPGP key byte[] key = sop.generateKey() .userId("Alice ") .generate() .getBytes(); // Extract the certificate (public key) byte[] cert = sop.extractCert() .key(key) .getBytes(); // Encrypt a message byte[] message = ... byte[] encrypted = sop.encrypt() .withCert(cert) .signWith(key) .plaintext(message) .getBytes(); // Decrypt a message ByteArrayAndResult messageAndVerifications = sop.decrypt() .verifyWith(cert) .withKey(key) .ciphertext(encrypted) .toByteArrayAndResult(); byte[] decrypted = messageAndVerifications.getBytes(); // Signature Verifications DecryptionResult messageInfo = messageAndVerifications.getResult(); List signatureVerifications = messageInfo.getVerifications(); ```
