Description:
------------
php 8+ with openssl

The openssl_cms_encrypt and openssl_pkcs7_encrypt function only allows an int as parameter for ciphers, referring to the enum php_openssl_cipher_type, that only contains ciphers, that are usually not recommended. Better options would be using AES_GCM,ChaCha20_Poly1305,AES_CTR... With openssl_encrypt we can use any cipher, because it resolves the string.

My suggestion would be to change the API to accept strings and deprecate the enum version, or else it would be necessary to map all new cipher methods in the future.

Test script:
---------------
    openssl_cms_encrypt(
        input_filename: $tempfileSigned,
        output_filename: $tempfileEncrypted,
        certificate: $recipientsCertificate,
        headers: [],
        flags: OPENSSL_CMS_BINARY | OPENSSL_CMS_NOSIGS | OPENSSL_CMS_NOVERIFY,
        encoding: OPENSSL_ENCODING_DER,
        cipher_algo: "aes-256-gcm"
    );


Expected result:
----------------
That the openssl function is executed and the cipher algo is resolved from the string.

Actual result:
--------------
It doesn't work with strings only a very short list of mapped ENUM.
