NAMESMIME_read_ASN1_ex, SMIME_read_ASN1 ​− parse S/MIME message
SYNOPSIS​ #include <openssl/asn1.h> ​ ​ ASN1_VALUE *SMIME_read_ASN1_ex(BIO *in, int flags, BIO **bcont, ​ const ASN1_ITEM *it, ASN1_VALUE **x, ​ OSSL_LIB_CTX *libctx, const char *propq); ​ ASN1_VALUE *SMIME_read_ASN1(BIO *in, BIO **bcont, const ASN1_ITEM *it);
DESCRIPTION​SMIME_read_ASN1_ex() parses a message in S/MIME format. ​in is a BIO to read the message from. If the flags argument contains CMS_BINARY then the input is assumed to be in binary format and is not translated to canonical form. If in addition SMIME_ASCIICRLF is set then the binary input is assumed to be followed by CR and LF characters, else only by an LF character. ​x can be used to optionally supply a previously created it ASN1_VALUE object (such as CMS_ContentInfo or PKCS7), it can be set to NULL. Valid values that can be used by ASN.1 structure it are ASN1_ITEM_rptr(PKCS7) or ASN1_ITEM_rptr(CMS_ContentInfo). Any algorithm fetches that occur during the operation will use the OSSL_LIB_CTX supplied in the libctx parameter, and use the property query string propq See ​‟ALGORITHM FETCHING” in crypto (7) for further details about algorithm fetching. If cleartext signing is used then the content is saved in a memory bio which is written to *bcont, otherwise *bcont is set to NULL. The parsed ASN1_VALUE structure is returned or NULL if an error occurred. ​SMIME_read_ASN1() is similar to SMIME_read_ASN1_ex() but sets the value of x to NULL and the value of flags to 0.
NOTESThe higher level functions SMIME_read_CMS_ex (3) and ​SMIME_read_PKCS7_ex (3) should be used instead of SMIME_read_ASN1_ex(). To support future functionality if bcont is not NULL *bcont should be initialized to NULL.
BUGSThe MIME parser used by SMIME_read_ASN1_ex() is somewhat primitive. While it will handle most S/MIME messages more complex compound formats may not work. The use of a memory BIO to hold the signed content limits the size of message which can be processed due to memory restraints: a streaming single pass option should be available.
RETURN VALUES​SMIME_read_ASN1_ex() and SMIME_read_ASN1() return a valid ASN1_VALUE structure or NULL if an error occurred. The error can be obtained from ​ERR_get_error (3).

HISTORYThe function SMIME_read_ASN1_ex() was added in OpenSSL 3.0.
