The main difference is that secp256k1 is a Koblitz curve, while secp256r1 is not. Koblitz curves are known to be a few bits weaker than other curves, but since we are talking about 256-bit curves, neither is broken in "5-10 years" unless there's a breakthrough.

The first link lets me verify a public key + message + signature combination. Do you know of some online site that will generate a signature given a private key and a message (just for playing around purposes of course -- your fair warning is very apt). – thanks_in_advance May 16 '17 at 1:05 The page shows the SSL/TLS capabilities of your web browser, determines supported TLS protocols and cipher suites, and marks if any of them are weak or insecure, displays a list of supported TLS extensions and key exchange groups.

OpenSSL supports many named curves (you can get a full list with the -list_curves switch), but, for web server keys, you’re limited to only two curves that are supported by all major browsers: secp256r1 (OpenSSL uses the name prime256v1) and secp384r1. Examples of signature algorithms are rsa_pkcs1_sha256 and ecdsa_secp256r1_sha256. Create a custom cipher rule When you create your own cipher rules for inclusion in a custom cipher group, the BIG-IP system builds a cipher string that includes or excludes the cipher suites and algorithms needed for negotiating SSL connections. Apr 15, 2016 · openssl ecparam -genkey -name secp256r1 > ecdsa.key That will just generate the key without the password and the need to remove it which is great if you're automating things somewhere. I've left my method above though as some other guides detail how to generate the key but not remove the password. secp256r1 and the other NIST curves are well known to possibly have NSA backdoors and therefore are likely NOT more secure than secp256k1. the constants used for the NIST curves use the output of SHA1 which is good, but the seed chosen to be hashed was apparently just a number with no explanation chosen by an NSA employee.

May 04, 2017 · Awesome answer - Especially the reboot twice hint! At least now RDP uses TLS 1.2. However, even with this, I still see TLS 1.0 and 1.1 being allowed even though it should be disabled: Enable TLS 1.2 strong cipher suites. Only applies to on-premise installations of Deep Security Manager. This page describes how to update the Deep Security Manager, Deep Security Agent and Deep Security Relay so that they use the TLS 1.2 strong cipher suites. Bug 1021897 - Enable curve secp521r1. ... It is a logical progression from suiteb (secp256r1 and secp384r1), so I would expect it to be a common choice.

Oct 30, 2013 · Thanks for the Article! It’s important to note that we’re not talking about traditional backdoors, but using weak seeds that give the NSA or anyone else aware of the weakness a strong foothold in cracking that which seems solid and safe. Hash Functions. Any hash function in the hashlib module (md5, sha1, sha224, sha256, sha384, sha512) will work, as will any hash function that implements the same interface / core functionality as the those in hashlib.

I am looking for a cross platform way to share public keys for ECDSA signing. I had a great thing going from a performance perspective with CngKey and the standard .NET crypto libraries, but then I couldn't figure out how a 33 (or 65) byte public key (using secp256r1/P256) was getting turned into 104 bytes by MS..

This specification defines algorithm encodings and representations enabling the Standards for Efficient Cryptography Group (SECG) elliptic curve "secp256k1" to be used for JSON Object Signing and Encryption (JOSE) and CBOR Object Signing and Encryption (COSE) messages. This comparison of TLS implementations compares several of the most notable libraries. There are several TLS implementations which are free software and open source. All comparison categories use the stable version of each implementation listed in the overview section. The comparison is limited to features that directly relate to the TLS protocol. Examples of signature algorithms are rsa_pkcs1_sha256 and ecdsa_secp256r1_sha256.

If ECC is selected as the certificate key algorithm in the Certificate Key Algorithm menu, you are prompted to choose the ECC key type (for user or server certificates only) to be set in the new certificate and the EC named curve to be used when generating the ECC key. Useful, free online tool for that converts text and strings to base58. No ads, nonsense or garbage, just a base58 converter. Press button, get result. Like it was said by @Tom Leek secp256r1 is P-256, secp384r1 is P-384 and secp521r1 is P-521. They are all part of the NSA suite B.. A Wikipedia article has a list of all implementation of curves. .
