in my sysroots/imx6ulevk/usr/lib I have

ls -la libssl*

libssl3.so
libssl.a
libssl.so -> libssl.so.1.0.0
libssl.so.1.0.0

ls -la libcrypt*

libcrypt.a
libcrypt_pic.a
libcrypt_pic.map
libcrypt.so -> ../../lib/libcrypt.so.1


but no libcrypto.so. I guess thats the reason why my ntp configure
script is complaining.

Some ideas how to get libcrypto.so in my /usr/lib folder in the yocto
sysroot?

some explenation whats the difference between libcrypt.so and libcrypto.so?

Best Regards,
