PGP requires partners to encrypt/decrypt and sign payloads with multiple keys, using `SHA384` for signing and `AES256` for encryption. Keys must be 2048+ bit RSA keys expiring in one year. JWE/JWS requires compact serialization, multiple key support, RSA-OAEP, ECDH-ES, and A256GCM encryption algorithms, with specific algorithms for signature creation. Both methods necessitate exchanging public-private keys with Google before development, with a one-year expiration for private keys.\n"]]
