sha256

I am working on an encryption method in the iPhone with the RSA encryption method, so far i could achieve getting the encryption string with this method, the string is successfully decrypted by the server. SecKeyRef keyRef = [self addPublicKey:pubKey]; SecKeyAlgorithm algorithm = kSecKeyAlgorithmRSAEncryptionOAEPSHA256; if (!keyRef) { return nil; } BOOL canEncrypt = SecKeyIsAlgorithmSupported(keyRef, kSecKeyOperationTypeEncrypt, algorithm); if (canEncrypt) { CFErrorRef error = NULL; NSData *encryptedData = (NSData *)CFBridgingRelease( SecKeyCreateEncryptedData(keyRef, algorithm, (__bridge

如果要删除本地的镜像，可以使用 docker image rm 命令，其格式为： $ docker image rm [选项] <镜像1> [<镜像2> ...] # 用 ID、镜像名、摘要删除镜像 其中， <镜像> 可以是 镜像短 ID 、 镜像长 ID 、 镜像名 或者 镜像摘要 。 比如我们有这么一些镜像： $ docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE centos latest 0584b3d2cf6d 3 weeks ago 196.5 MB redis alpine 501ad78535f0 3 weeks ago 21.03 MB docker latest cf693ec9b5c7 3 weeks ago 105.1 MB nginx latest e43d811ce2f4 5 weeks ago 181.5 MB 我们可以用镜像的完整 ID，也称为 长 ID ，来删除镜像。使用脚本的时候可能会用长 ID，但是人工输入就太累了，所以更多的时候是用 短 ID 来删除镜像。 docker image ls 默认列出的就已经是短 ID 了，一般取前3个字符以上，只要足够区分于别的镜像就可以了。 比如这里，如果我们要删除 redis:alpine 镜像，可以执行： $ docker image rm 501

I'm working for a Fortune 100 company and I'm thrown into being tasked with security moving from SHA1 to SHA-2 . This is not my area of expertise, but as I study cryptography I am questioning the outdated information etc... SHA-2 is obviously needed over SHA-1 but when the security team KNOWS that the hashing of password + salt is using SHA, with GPU being so ridiculously fast at cracking billions of hashes - I do not get why for passwords i'm not being told to use bcrypt or another equivalent that is slow , WHY? I'm shown a powerpoint slide in which i'm told to create my salt 60,000 times. I

I have the following entry in the signature of my jar file Timestamped by "CN=GlobalSign TSA for Advanced - G3 - 001-02, O=GMO GlobalSign K.K., C=JP" on Mo Apr 10 11:48:34 UTC 2017 Timestamp digest algorithm: SHA-256 Timestamp signature algorithm: SHA256withRSA, 2048-bit key I already found out that the SHA-256 at the timestamp digest algoirthm and the SHA256withRSA at the timestamp signature algorithm are causing problems when running the jar file on a system which java version is below 1.7.0_76 (jar file is treaded as unsigned). Can somebody tell me from which java versions on these two

Is it possible to use SHA256CryptoServiceProvider and related SHA2 providers on Windows XP? I know the providers use the cryptography services that are included in Vista and above is it possible to install these services in XP from Microsoft? EDIT: I should've provided more information the documentation on the MSDN is wrong in regards to this being supported in Windows XP. See http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=355031 where this is acknowledged and accepted by Microsoft as by design. However there is no work around listed anywhere (that I saw) so I

just looking for some advise. I have a website with around 2500 users - small but growing. I built it with using SHA1 encryption on the passwords. I've since read the SHA1 is insecure and would like to change to say SHA256 with a Salt. Does anyone have any advice on how to make a transition like this? Would be great if I could decrypt the passwords and just re-hash them but it doesn't appear doing able. thx Adam The usual way of going about this is this: Make the hashed-password column larger to accommodate a sha256 hash, and add a 'salt' column Set the salt field to NULL initially, and adjust
