My own conclusion is that 2048 is not a dead duck and using this key length remains a valid decision and is very likely to remain so for the next 5 years at least.The US NIST makes a similar recommendation and
Lifetime of data RSA key size Up to 2010 1024 bits Up to 2030 2048 bits Up to 2031 onwards 3072 bitsRecommended RSA key sizes depending on lifetime of confidential data.Other authors have been more conservative. Ferguson & Schneier (2003) in Practical Cryptography implied that 2048 bits ...
The defined keySize is 1024 Bit, which means I should get back a 128 Byte key. But when I'm using the methods SecKey.CreateRandomKey or SecKey.GenerateKeyPair I always get a 140 byte long key back. Since I have to send the public key in my app to an otrher system, I need a ...
According to therecommendationof the National Institute of Standards and Technology (NIST), the smallest RSA key size that can be considered secure is 2,048 bits. This means approximately 600 digits, but in many cases larger keys of 3,072 or 4,096 bits are also used. There, the number of...
Would we include recommendation on key size? Some people intentionally want to use 4096 bit key. Would they take advice? The document could explain the trade-off between security, compatibility, and other factors But seems hardware routers don’t support roots more than 2048 (Cisco) Iñigo sai...
TLS server authentication is becoming more secure across Windows. Weak RSA key lengths for certificates will be deprecated on future Windows OS releases later this year. Specifically, this affects TL... Is this recommendation in the Microsoft Trusted Root Program still valid?

具体的,通过JCE实现模块的KeyPairGenerator类来获得密码卡内部的公钥和假私钥。KeyPairGenerator类可通过public static KeyPairGenerator getInstance(String algorithm,Provider provider)方法实例化一个对象,其中algorithm参数指定密钥对的算法,provider参数指定服务提供商。public void initialize(int keysize,SecureRandom random...
While I'm sure there are many pointed problems aside from key size, the fact that their have been other issues do not mean key size does not, or will not, factor into the security of the system. To use your examples, Poodle can be mitigated by disabling SSLv3 (something I had ...
1 Introduction The RSA [13] is one of the standard public-key cryptosystems. The security of RSA relies on a fact that factoring huge integers, which is used as a public-key in RSA, is infeasible. Thus the key-length of RSA is chosen so as to avoid such factorization. In the past,...
