PKCS7_DETACHED

PKCS7_DETACHED is one of the accepted parameters for:

• openssl_pkcs7_verify parameter #2 (optionally as a bitmask)
• openssl_pkcs7_sign parameter #6 (optionally as a bitmask)
• openssl_pkcs7_encrypt parameter #5 (optionally as a bitmask)

PKCS7 CONSTANT: PKCS7_DETACHED — When signing a message, use cleartext signing with the MIME type "multipart/signed". This is the default if you do not specify any $flags to openssl_pkcs7_sign. If you turn this option off, the message will be signed using opaque signing, which is more resistant to translation by mail relays but cannot be read by mail agents that do not support S/MIME.
