From eb845bea4c320d6037103ea1d107bbdefdc0bde7 Mon Sep 17 00:00:00 2001 From: knu Date: Tue, 23 Feb 2010 15:51:01 +0000 Subject: * ext/openssl/ossl_digest.c (GetDigestPtr): Allow to pass the OpenSSL::Digest class in place of where either an instance of the class or the algorithm name was demanded. For example, OpenSSL::HMAC.digest(OpenSSL::Digest::SHA1, key, data) is now accepted as well as the usual OpenSSL::HMAC.digest(OpenSSL::Digest::SHA1.new, key, data) and OpenSSL::HMAC.digest("SHA1", key, data). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@26739 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ext/openssl/ossl_digest.c | 19 +++++++++++++------ 1 file changed, 13 insertions(+), 6 deletions(-) (limited to 'ext') diff --git a/ext/openssl/ossl_digest.c b/ext/openssl/ossl_digest.c index 9b8ced5233..30478911ba 100644 --- a/ext/openssl/ossl_digest.c +++ b/ext/openssl/ossl_digest.c @@ -37,18 +37,25 @@ GetDigestPtr(VALUE obj) { const EVP_MD *md; - if (TYPE(obj) == T_STRING) { - const char *name = StringValueCStr(obj); + if (TYPE(obj) == T_CLASS) { + EVP_MD_CTX *ctx; + VALUE digest = rb_funcall(obj, rb_intern("new"), 0, 0); - md = EVP_get_digestbyname(name); - if (!md) - ossl_raise(rb_eRuntimeError, "Unsupported digest algorithm (%s).", name); - } else { + SafeGetDigest(digest, ctx); + + md = EVP_MD_CTX_md(ctx); + } else if (rb_obj_is_kind_of(obj, cDigest)) { EVP_MD_CTX *ctx; SafeGetDigest(obj, ctx); md = EVP_MD_CTX_md(ctx); + } else { + const char *name = StringValueCStr(obj); + + md = EVP_get_digestbyname(name); + if (!md) + ossl_raise(rb_eRuntimeError, "Unsupported digest algorithm (%s).", name); } return md; -- cgit v1.2.3
