The RSA public key algorithm needs to select MPILIB directly in Kconfig as the 'select' directive is not recursive and is thus MPILIB is not enabled by selecting MPILIB_EXTRA. Without this, the following errors can occur: crypto/built-in.o: In function `RSA_verify_signature': rsa.c:(.text+0x1d347): undefined reference to `mpi_get_nbits' rsa.c:(.text+0x1d354): undefined reference to `mpi_get_nbits' rsa.c:(.text+0x1d36e): undefined reference to `mpi_cmp_ui' rsa.c:(.text+0x1d382): undefined reference to `mpi_cmp' rsa.c:(.text+0x1d391): undefined reference to `mpi_alloc' rsa.c:(.text+0x1d3b0): undefined reference to `mpi_powm' rsa.c:(.text+0x1d3c3): undefined reference to `mpi_free' rsa.c:(.text+0x1d3d8): undefined reference to `mpi_get_buffer' rsa.c:(.text+0x1d4d4): undefined reference to `mpi_free' rsa.c:(.text+0x1d503): undefined reference to `mpi_get_nbits' Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Randy Dunlap <rdunlap@infradead.org>

appropriate hash algorithms (such as SHA-1) must be available.
