This prints the SHA1 sum I wrote about few days ago. $ openssl md5 /etc/passwd MD5(/etc/passwd)= 4e85dafb634ceb6afc3acbf2e1050151 $openssl help Standard commands asn1parse ca ciphers crl crl2pkcs7 dgst dh dhparam dsa dsaparam ec ecparam enc engine errstr gendh gendsa genrsa nseq ocsp passwd pkcs12 pkcs7 pkcs8 prime rand req rsa rsautl s_client s_server s_time sess_id smime speed spkac verify version x509 You can invoke several commands for creating public keypairs, prime numbers, random data, base64 encoding and so on. You also create SSL self signed certificate and private key using this utility. $ openssl rand -out randdata.bin 2048 will generate random data of size 2048 bytes. Several possibilities are there. You can encrypt files, decrypt them , use salt, you can do a whole bunch of stuff. If you simply enter openssl you can enter these commands within the openssl shell interface. -Girish -- Gayatri Hitech web: http://gayatri-hitech.com SpamCheetah Spam filter: http://spam-cheetah.com _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
