On spotting the example code in Ed25519(7) I tried it, and it segfaulted: #0 0x00007fcedd3e47e0 in PEM_write_bio_PrivateKey () from /lib64/libcrypto.so.1.1 #1 0x00007fcedd3e4afb in PEM_write_PrivateKey () from /lib64/libcrypto.so.1.1 #2 0x0000000000400744 in main () at src/ed25519_gen_privkey.c:11 This a self-built openssl from today's master. I'm unsure how to get debuginfo for it, for better detail. Given how simple PEM_write_bio_PrivateKey() is, I assume it's gone on to PEM_write_bio_PrivateKey_traditional(). Any clues? -- Thanks, Jeremy -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
