Read legacy encrypted messages¶

When working with an older protocol that expects NIP-04 encryption, select it explicitly on the signer:

String ciphertext = signer.encrypt(
    "legacy message", recipient,
    NostrSigner.EncryptAlgo.NIP04).await();

String plaintext = signer.decrypt(
    ciphertext, sender,
    NostrSigner.EncryptAlgo.NIP04).await();

Tip

For new encrypted data, prefer NIP-44.
