in PHP how do i create the full public key from a compressed one?
my test key is 026a04ab98d9e4774ad806e302dddeb63bea16b5cb5f223ee77478e861bb583eb3
and the uncompressed one is 6a04ab98d9e4774ad806e302dddeb63bea16b5cb5f223ee77478e861bb583eb3 36b6fbcb60b5b3d4f1551ac45e5ffc4936466e7d98f6c7c0ec736539f74691a6
can this be done via openssl?
thanks for any helpful answer!!
