| 56 | .Sh NAME | ||

| 58 | .Nd generic S/MIME message parser | ||
| 59 | .Sh SYNOPSIS | ||
| 60 | .In openssl/asn1.h | ||
| 61 | .Ft ASN1_VALUE * | ||
| 62 | .Fo SMIME_read_ASN1 | ||
| 63 | .Fa "BIO *in_bio" | ||

| 66 | .Fc | ||
| 67 | .Sh DESCRIPTION | ||
| 68 | .Fn SMIME_read_ASN1 | ||
| 69 | reads a message in S/MIME format from | ||
| 70 | .Fa in_bio . | ||
| 71 | .Pp | ||
| 72 | If the message uses cleartext signing, the content is saved in a memory | ||
| 73 | .Vt BIO | ||
| 74 | which is written to | ||
| 75 | .Pf * Fa out_bio . | ||
| 76 | Otherwise, | ||
| 77 | .Pf * Fa out_bio | ||
| 78 | is set to | ||
| 79 | .Dv NULL . | ||
| 80 | .Pp | ||
| 81 | To support future functionality, if | ||
| 82 | .Fa out_bio | ||
| 83 | is not | ||
| 84 | .Dv NULL , | ||
| 85 | .Pf * Fa out_bio | ||
| 86 | should be initialized to | ||
| 87 | .Dv NULL | ||
| 88 | before calling | ||
| 89 | .Fn SMIME_read_ASN1 . | ||
| 90 | .Sh RETURN VALUES | ||
| 91 | .Fn SMIME_read_ASN1 | ||
| 92 | returns a newly allocated object of type | ||
| 93 | .Fa it | ||
| 94 | or | ||
| 95 | .Dv NULL | ||
| 96 | if an error occurred. | ||
| 97 | The error can be obtained from | ||

| 106 | .Sh HISTORY | ||
| 107 | .Fn SMIME_read_ASN1 | ||
| 108 | first appeared in OpenSSL 0.9.8h and has been available since | ||
| 109 | .Ox 4.5 . | ||
| 110 | .Sh BUGS | ||
| 111 | The MIME parser used by | ||
| 112 | .Fn SMIME_read_ASN1 | ||
| 113 | is somewhat primitive. | ||
| 114 | While it will handle most S/MIME messages, more complex compound | ||
| 115 | formats may not work. | ||
| 116 | .Pp | ||
| 117 | The parser assumes that the | ||
| 118 | structure is always base64 encoded, and it will not handle the case | ||
| 119 | where it is in binary format or uses quoted printable format. | ||
| 120 | .Pp | ||
| 121 | The use of a memory | ||
| 122 | to hold the signed content limits the size of the message which can | ||
| 123 | be processed due to memory restraints: a streaming single pass | ||
| 124 | option should be available. | ||
