나 의 누 이, 나 의 신 부 는 잠 근 동 산 이 요 덮 은 우 물 이 요 봉 한 샘 이 로 구

to znamená, že lze poslat zapečetěná data více příjemcům (za předpokladu, že máme jejích veřejné klíče).
openssl_seal() seals (encrypts) data by using rc4 with a randomly generated secret key. the key is encrypted with each of the public keys associated with the identifiers in pub_key_ids and each encrypted key is returned in env_keys. this means that one can send sealed data to multiple recipients (provided one has obtained their public keys). each recipient must receive both the sealed data and the envelope key that was encrypted with the recipient's public key.

při úspěchu vrací délku zapečetěných dat, při chybě false.
