| 56 | .Nd decrypt content from a PKCS#7 envelopedData structure | ||
| 57 | .Sh SYNOPSIS | ||
| 58 | .In openssl/pkcs7.h | ||
| 59 | .Ft int | ||
| 60 | .Fo PKCS7_decrypt | ||
| 61 | .Fa "PKCS7 *p7" | ||

| 67 | .Sh DESCRIPTION | ||
| 68 | .Fn PKCS7_decrypt | ||
| 69 | extracts and decrypts the content from a PKCS#7 envelopedData structure. | ||
| 70 | .Fa pkey | ||
| 71 | is the private key of the recipient, | ||
| 72 | .Fa cert | ||
| 73 | is the recipient's certificate, | ||
| 74 | .Fa data | ||
| 75 | is a | ||
| 76 | .Vt BIO | ||
| 77 | to write the content to and | ||
| 78 | .Fa flags | ||
| 79 | is an optional set of flags. | ||
| 80 | .Pp | ||
| 81 | Although the recipient's certificate is not needed to decrypt the data, | ||
| 82 | it is needed to locate the appropriate recipients | ||
| 83 | in the PKCS#7 structure. | ||
| 84 | .Pp | ||
| 85 | If the | ||
| 86 | .Dv PKCS7_TEXT | ||
| 87 | .Fa flag | ||
| 88 | is set, MIME headers for type | ||
| 89 | .Sy text/plain | ||
| 90 | are deleted from the content. | ||
| 91 | If the content is not of type | ||
| 92 | .Sy text/plain , | ||
| 93 | an error is returned. | ||
| 94 | .Sh RETURN VALUES | ||
| 95 | .Fn PKCS7_decrypt | ||
| 96 | returns 1 for success or 0 for failure. | ||
| 97 | .Pp | ||
| 98 | The error can be obtained from | ||

| 104 | .Sh HISTORY | ||
| 105 | .Fn PKCS7_decrypt | ||
| 106 | first appeared in OpenSSL 0.9.5 and has been available since | ||
| 107 | .Ox 2.7 . | ||
| 108 | .Sh BUGS | ||
| 109 | .Fn PKCS7_decrypt | ||
| 110 | must be passed the correct recipient key and certificate. | ||
| 111 | It would be better if it could look up the correct key and certificate | ||
| 112 | from a database. | ||
| 113 | .Pp | ||
| 114 | The lack of single pass processing and need to hold all data in memory | ||
| 115 | as mentioned in | ||
| 116 | .Xr PKCS7_sign 3 | ||
| 117 | also applies to | ||
| 118 | .Fn PKCS7_decrypt . | ||
