# PKCS12\_decrypt\_skey(3ssl)

PKCS12 shrouded keyBag decrypt functions

## NAME

PKCS12\_decrypt\_skey, PKCS12\_decrypt\_skey\_ex - PKCS12 shrouded keyBag decrypt functions

## SYNOPSIS

```
 #include <openssl/pkcs12.h>
 PKCS8_PRIV_KEY_INFO *PKCS12_decrypt_skey(const PKCS12_SAFEBAG *bag,
                                          const char *pass, int passlen);
 PKCS8_PRIV_KEY_INFO *PKCS12_decrypt_skey_ex(const PKCS12_SAFEBAG *bag,
                                             const char *pass, int passlen,
                                             OSSL_LIB_CTX *ctx,
                                             const char *propq);
```

## DESCRIPTION

**PKCS12\_decrypt\_skey()** Decrypt the PKCS#8 shrouded keybag contained within *bag* using the supplied password *pass* of length *passlen*.

**PKCS12\_decrypt\_skey\_ex()** is similar to the above but allows for a library context *ctx* and property query *propq* to be used to select algorithm implementations.

## RETURN VALUES

Both functions will return the decrypted key or NULL if an error occurred.

## CONFORMING TO

IETF RFC 7292 (\<https://tools.ietf.org/html/rfc7292\>)
