Symmetric 256-bit encryption. RSA public-key SHA-2 algorithm (supports hash functions: 256, 384, 512) ECC public-key cryptography (supports hash functions: 256 and 384) Supports 2048-bit public key encryption (3072-bit and 4096-bit available)
The number (n) must be >=3. While 2 is a prime number, for our purposes we have no interest in numbers less than 3. Do a bitwise and (n&1). If the result is not 0 then we know the number is even and can throw it out. Check that n%p is 0 (in other words, that n is not divisible evenly by p) for all primes <1000.

Yeah, I got up to 1024 bits but then I ran out of lifelines and regis goaded me into picking the wrong factor. --- to factor a 1620-bit number in one year would require 1.6 x 10^15 Pentium-class machines, each with 120 Terrabytes of physical RAM. Good luck. Share. twitter facebook linkedin. RSA-2048 has 617 decimal digits (2,048 bits). It is the largest of the RSA numbers and carried the largest cash prize for its factorization, $200,000. The RSA-2048 may not be factorizable for many years to come, unless considerable advances are made in integer factorization or computational power in the near future. 8 bit 16 bit 32 bit 64 bit 256 bit 512 bit 1024 bit 2048 bit Random Number Generator.

java - How to split the 2048 bits BigInteger into words
I have a key that contains 2048 bit BigInteger number. I want to break it into words with a fixed number of 64 bits, and then compute the exclusive OR of all those words; can anyone help me to impl
A 2,048-bit encryption key in binary is equivalent to a 617-digit number using decimal digits -- not an easy number to guess if you don't know it. It generates RSA public key as well as the private key of size 512 bit, 1024 bit, 2048 bit, 3072 bit and 4096 bit with Base64 encoded. By default, the private key is generated in PKCS#8 format and the public key is generated in X.509 format . I have a key that contains 2048 bit BigInteger number. I want to break it into words with a fixed number of 64 bits, and then compute the exclusive OR of all those words; can anyone help me to impl Here are the results on my home PC, which is decent but far from exceptional as far as number-crunching power goes: sign verify sign/s verify/s rsa 1024 bits 0.000273s 0.000017s 3662.2 59513.0 rsa 2048 bits 0.001994s 0.000052s 501.5 19254.5 rsa 4096 bits 0.014438s 0.000219s 69.3 4560.3 Factoring 2048 bit number is easy?
