From 1684c8f398922065a97e7da4dac4ac6a33cc5218 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Parm=C3=A9nides=20GV?= Date: Wed, 9 Apr 2014 16:03:55 +0200 Subject: Back to the standard "app" module. This return to "app" instead of "bitmask_android" is due to this reading: https://developer.android.com/sdk/installing/studio-build.html#projectStructure I'll have to tweak the final apk name in build.gradle. --- app/openssl/crypto/asn1/x_name.c | 520 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 520 insertions(+) create mode 100644 app/openssl/crypto/asn1/x_name.c (limited to 'app/openssl/crypto/asn1/x_name.c') diff --git a/app/openssl/crypto/asn1/x_name.c b/app/openssl/crypto/asn1/x_name.c new file mode 100644 index 00000000..49be08b4 --- /dev/null +++ b/app/openssl/crypto/asn1/x_name.c @@ -0,0 +1,520 @@ +/* crypto/asn1/x_name.c */ +/* Copyright (C) 1995-1998 Eric Young (eay@cryptsoft.com) + * All rights reserved. + * + * This package is an SSL implementation written + * by Eric Young (eay@cryptsoft.com). + * The implementation was written so as to conform with Netscapes SSL. + * + * This library is free for commercial and non-commercial use as long as + * the following conditions are aheared to.
