Generator Online SHA1

I need to get a key for DES (ECB-EDE). For this I have to use PBKDF2-SHA1 (but not HMAC-SHA1!). But I haven't seen any PBKDF2 implementations with standart SHA1. The ORACLE-JAVA documentation also says only about PBKDF2WithHmacSHA1.

Could you help with the implementation of PBKDF2 with standart SHA1?A reference to an implementation of PBKDF2WithHmacSHA1: this.

I don't want to calculate a file's checksum, just to know if a given string is a valid checksum

I have to write method like this:

boolean isHash(String str){  ...}

Method should return true if input string is md5 hash or sha1 hash or sha256 hash.

Is it possible to implement such method ?

[]byte to string raises an error.string([]byte[:n]) raises an error too.By the way, for example, sha1 value to string for filename.Does it need utf-8 or any other encoding set explicitly? Thanks!

We are upgrading our website from ASP.NET 4.61 to 4.8 and running into the following issue with our certificate. https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/retargeting/4.5.2-4.7.1#default-signedxml-and-signedxms-algorithms-changed-to-sha256

Our cert is SHA2 but the SignedXML and SignedXMS algorithm is SHA1 in the cert. I would like to get our cert re-issued with SignedXML and SignedXMS algorithms as SHA256, which is the default for .NET 4.71 and up.

*Question is, would the re-issued cert work in our current production environment with .NET 4.61 before the next release. Or would we have to install the new cert with the release?

If my understanding is correct, the algorithm is set in the certificate for the crypto service provider and would use the SHA256 algorithm from the re-issued certificate without modifications?

I do see in the registry under .../SCHANNEL/Hashes/SHA256 is enabled.
