Oct 23, 2015  Help me - SSH key generation failed. I installed Rhel 7 in my laptop and i could not start the sshd session. It always says that as below: sshd-keygen: generating ssh2 rsa host key failed. I tried to generate the key manually, but it not works. For that you have to generate a key pair on the client machine, not the server (if you want. If you are a new customer, register now for access to product evaluations and purchasing capabilities.

Hi Mithun,

The command -generate-key may be used along with the option -batch for unattended key generation. This is the most flexible way of generating keys, but it is also the most complex one. Consider using the quick key manipulation interface described in the previous subsection “The quick key. Jul 22, 2015  Hi, even when I run the mapping outside the workflow it fails. I have seen that with 50,000 rows it run ok but if I have mora than 50,000 rows the mapping fails. Dismiss Join GitHub today. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. There is no way to generate a secure key-pair from the password 'puppies'. If you are using a 256-bit elliptic curve and want the full 128-bit security it can offer, any password from which you directly derive a key needs to have over 100 bits of entropy.

I noticed embedded board key generation times vary by OS and OpenSSL version after converting a Altera Atlas FPGA SoC HPS from original 2013 Yocto Linux to latest Ubuntu. Under the old Yocto, key generation occasionally took up to 2 minutes. Same board under Ubuntu 16.04, 2048 RSA keys take consistently 2-5 seconds, while 3072 keys need around 8-16 seconds. Even running the system single core, the numbers don't change (on a low utilized system, using OS built-in /dev/urandom).
While I am on a different CPU and OS (32bit ARM v7 900Mhz dual core, 1GB 400Mhz RAM), your e500 PowerPC can't be to far behind. Your numbers seem to be off by a magnitude. You mentioned using a external HW RNG, could that be it?

Cheers,

I'm afraid you will have to look at the OpenSSL source code, I haven't
paid much attention to that CPU recently.

Hi Jakob,
Can you please give me some reference/example of bignum optimization which I can check on powerpc architectures.
Is this any specific instruction set addition? or something more generic?
Thanks & Regards

I believe this is a CPU intensive operation (if VxWorks can do
this, try observing the CPU load during).
Potential improvements:
1. Check if the CPU specific bignum optimizations for your CPU
variant have been enabled via the libcrypto CPU detection code
(for example, there are optimizations for different ARM cortex
variants).
2. Faster CPU (expensive obviously).
3. Do the generation in the background before the keypair is
needed, at a time when the extra CPU load is less of a problem.
Enjoy

Hi
I have a embedded board P1010 RDB running openssl on VXWORKS 5.4 .
I am providing entropy to openssl by using RAND_seed from a HW RNG.
My average generation time for RSA 2048 key pair is 2 Minutes and 3072 is 8 minutes.

Key generation is the process of generating keys in cryptography. A key is used to encrypt and decrypt whatever data is being encrypted/decrypted.

A device or program used to generate keys is called a key generator or keygen.

Generation in cryptography[edit]

Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. The public key is made available to anyone (often by means of a digital certificate). A sender encrypts data with the receiver's public key; only the holder of the private key can decrypt this data.

Since public-key algorithms tend to be much slower than symmetric-key algorithms, modern systems such as TLS and SSH use a combination of the two: one party receives the other's public key, and encrypts a small piece of data (either a symmetric key or some data used to generate it). The remainder of the conversation uses a (typically faster) symmetric-key algorithm for encryption.

Computer cryptography uses integers for keys. In some cases keys are randomly generated using a random number generator (RNG) or pseudorandom number generator (PRNG). A PRNG is a computeralgorithm that produces data that appears random under analysis. PRNGs that use system entropy to seed data generally produce better results, since this makes the initial conditions of the PRNG much more difficult for an attacker to guess. Another way to generate randomness is to utilize information outside the system. veracrypt (a disk encryption software) utilizes user mouse movements to generate unique seeds, in which users are encouraged to move their mouse sporadically. In other situations, the key is derived deterministically using a passphrase and a key derivation function.

Many modern protocols are designed to have forward secrecy, which requires generating a fresh new shared key for each session.

Classic cryptosystems invariably generate two identical keys at one end of the communication link and somehow transport one of the keys to the other end of the link.However, it simplifies key management to use Diffie–Hellman key exchange instead.

The simplest method to read encrypted data without actually decrypting it is a brute-force attack—simply attempting every number, up to the maximum length of the key. Therefore, it is important to use a sufficiently long key length; longer keys take exponentially longer to attack, rendering a brute-force attack impractical. Currently, key lengths of 128 bits (for symmetric key algorithms) and 2048 bits (for public-key algorithms) are common.

Generation in physical layer[edit]

Wireless channels[edit]

A wireless channel is characterized by its two end users. By transmitting pilot signals, these two users can estimate the channel between them and use the channel information to generate a key which is secret only to them.[1] The common secret key for a group of users can be generated based on the channel of each pair of users.[2]

Optical fiber[edit]

A key can also be generated by exploiting the phase fluctuation in a fiber link.[clarification needed]

  • Distributed key generation: For some protocols, no party should be in the sole possession of the secret key. Rather, during distributed key generation, every party obtains a share of the key. A threshold of the participating parties need to cooperate to achieve a cryptographic task, such as decrypting a message.
