Key-size validation issue
WinSCP version: 5.13.3
Windows version: Windows 10 Enterprise, 10.0.16299 Build 16299
I am trying to generate ECDSA keypairs using the SSH Key Generator (/usr/bin/) tool. Using the -b option to generate a 512 bits key like this (PowerShell syntax):
The following error shows:
However, when I change my call to use the 521, a keypair is generated successfully.
I haven't been able to validate if the keypair works (and is actually 512 bits), but I'd expect it to, as I can't imagine a keypair can actually be generated with 521 bits.

. "C:/Program Files/Git/usr/bin/ssh-[KEYGENERATOR].exe" -t 'ecdsa' -f 'C:\temp\ecdsa-key' -b 512
Notice the 521, where I expected a 512.Invalid ECDSA key length: valid lengths are 256, 384 or 521 bits
However, when I change my call to use the 521, a keypair is generated successfully.
