From dafbb1b3e67a1a2fa7ff847fc762c0d9bedf5213 Mon Sep 17 00:00:00 2001 From: Kazuki Yamaguchi Date: Tue, 21 Apr 2020 02:12:29 +0900 Subject: pkey: add PKey#inspect and #oid Implement OpenSSL::PKey::PKey#oid as a wrapper around EVP_PKEY_id(). This allows user code to check the type of a PKey object. EVP_PKEY can have a pkey type for which we do not provide a dedicated subclass. In other words, an EVP_PKEY that is not any of {RSA,DSA,DH,EC} can exist. It is currently not possible to distinguish such a pkey. Also, implement PKey#inspect to include the key type for convenience. --- ext/openssl/ossl_pkey.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) (limited to 'ext') diff --git a/ext/openssl/ossl_pkey.c b/ext/openssl/ossl_pkey.c index fc08ebf5..23204087 100644 --- a/ext/openssl/ossl_pkey.c +++ b/ext/openssl/ossl_pkey.c @@ -299,6 +299,42 @@ ossl_pkey_initialize(VALUE self) return self; } +/* + * call-seq: + * pkey.oid -> string + * + * Returns the short name of the OID associated with _pkey_. + */ +static VALUE +ossl_pkey_oid(VALUE self) +{ + EVP_PKEY *pkey; + int nid; + + GetPKey(self, pkey); + nid = EVP_PKEY_id(pkey); + return rb_str_new_cstr(OBJ_nid2sn(nid)); +} + +/* + * call-seq: + * pkey.inspect -> string + * + * Returns a string describing the PKey object. + */ +static VALUE +ossl_pkey_inspect(VALUE self) +{ + EVP_PKEY *pkey; + int nid; + + GetPKey(self, pkey); + nid = EVP_PKEY_id(pkey); + return rb_sprintf("#<%"PRIsVALUE":%p oid=%s>", + rb_class_name(CLASS_OF(self)), (void *)self, + OBJ_nid2sn(nid)); +} + static VALUE do_pkcs8_export(int argc, VALUE *argv, VALUE self, int to_der) { @@ -615,6 +651,8 @@ Init_ossl_pkey(void) rb_define_alloc_func(cPKey, ossl_pkey_alloc); rb_define_method(cPKey, "initialize", ossl_pkey_initialize, 0); + rb_define_method(cPKey, "oid", ossl_pkey_oid, 0); + rb_define_method(cPKey, "inspect", ossl_pkey_inspect, 0); rb_define_method(cPKey, "private_to_der", ossl_pkey_private_to_der, -1); rb_define_method(cPKey, "private_to_pem", ossl_pkey_private_to_pem, -1); rb_define_method(cPKey, "public_to_der", ossl_pkey_public_to_der, 0); -- cgit v1.2.3
