Support for RSASSA-PKCS1-v1_5 with SHA1 digest

[cocool97]

I'm maintaining adb_client, a rust crate used to communicate using Android devices over ADB protocol. I'd like to move from rsa crate to ring to handle authentication (as rsa currently has a known security vulnerability, and as I'm already depending on ring through rcgen(rustls))

When authenticating, devices need to sign random data using Pkcs1v1.5 with a SHA1 digest. rsa crate is providing this feature, but did not find any way to achieve this using ring crate .

Are you planning to provide a static RSA_PKCS1_SHA1 implementing RsaEncoding trait ? Or is there another way to achieve this ?
