## Invalid key length
According to the src code check on pbkdf2.c:223:
``` if (ctx->lower_bound_checks != 0
&& p->data_size < KDF_PBKDF2_MIN_PASSWORD_LEN) {
ERR_raise(ERR_LIB_PROV, PROV_R_INVALID_KEY_LENGTH);
return 0;
}
```
And from pbkdf2.c:53:
`#define KDF_PBKDF2_MIN_PASSWORD_LEN (8)`
One needs to use password string >= 8 to export p12.
## MAC support issue
With valid key length:
One still gets error:
```
Error creating PKCS12 MAC; no PKCS12KDF support?
Use -nomac if MAC not required and PKCS12KDF support not available.
