Crypto: RSA Sign, field hash

[aslan]

Crypto: RSA Sign, accepts hash with type byte array
SHA-256 Hash i get hash with type string but I can’t convey in Crypto: RSA Sign in the field hash.
how can i convert hash type string to hash type byte array ?
I use the Crypto module version: 2.116

@aslan Please check your array of bytes. It looks like you placed multiple values into a single item of bytes array

Try to describe your use case in general and we will try to help you.

I pass the text to the block SHA-256 Hash and I get a hash of type string,
now i need to convert to type byte array, to pass to the block Crypto: RSA Sign

[OlegSotnikov]

Start from proper conversion of your PEM (I assume you use PEM encoded keys) to universal bytes. Use block

[aslan]

I use a block Crypto: RSA Generate key, that returns a key with a type byte array

[aslan]

now everything works
