| 20 | .Sh NAME | ||
| 21 | .Nm ASN1_item_digest | ||
| 22 | .Nd DER-encode and hash an ASN.1 value | ||
| 23 | .Sh SYNOPSIS | ||
| 24 | .In openssl/x509.h | ||
| 25 | .Ft int | ||
| 26 | .Fo ASN1_item_digest | ||
| 27 | .Fa "const ASN1_ITEM *it" | ||
| 28 | .Fa "const EVP_MD *type" | ||
| 29 | .Fa "void *val_in" | ||

| 33 | .Sh DESCRIPTION | ||
| 34 | .Fn ASN1_item_digest | ||
| 35 | assumes that | ||
| 36 | .Fa val_in | ||
| 37 | is an | ||
| 38 | .Vt ASN1_VALUE | ||
| 39 | of the type specified by | ||
| 40 | .Fa it , | ||
| 41 | encodes it into DER format by calling | ||
| 42 | .Xr ASN1_item_i2d 3 , | ||
| 43 | hashes the resulting byte array using the digest | ||
| 44 | .Fa type | ||
| 45 | by calling | ||
| 46 | .Xr EVP_Digest 3 , | ||
| 47 | places the digest value into | ||
| 48 | .Pf * Fa md , | ||
| 49 | and, unless | ||
| 50 | .Fa s | ||
| 51 | is | ||
| 52 | .Dv NULL , | ||
| 53 | places the length in bytes of the digest into | ||
| 54 | .Pf * Fa s . | ||
| 55 | Providing a buffer | ||
| 56 | .Pf * Fa md | ||
| 57 | large enough to contain the digest is the responsibility of the caller; | ||
| 58 | providing a buffer of | ||
| 59 | .Dv EVP_MAX_MD_SIZE | ||
| 60 | bytes is recommended. | ||
| 61 | .Sh RETURN VALUES | ||
| 62 | .Fn ASN1_item_digest | ||
| 63 | returns 1 for success or 0 if encoding or hashing fails. | ||

| 68 | .Sh HISTORY | ||
| 69 | .Fn ASN1_item_digest | ||
| 70 | first appeared in OpenSSL 0.9.7 and has been available since | ||
