is there built in method in ruby, or there easy way this?

best regards

you can use ruby's base64 module re-encode string. module take correct padding account:

require "base64"  str = "miiepaibaakcaqeayue3zaacnx50xrvh6csl05yjyxzrpmkfqlkfn4qfrbbkgogfy7nlf..." b64 = base64.encode64(base64.decode64(str)) pem = "-----begin certificate-----\n" << b64 << "-----end certificate-----\n"  puts pem # -----begin certificate----- # miiepaibaakcaqeayue3zaacnx50xrvh6csl05yjyxzrpmkfqlkfn4qfrbbk # gogfy7nlfniccchg1kux8+bi5txoovf28qa7drizrz6hnyrxvmjkklhkczmg # hapefss3swk2knw6bzvqmo20fidib/fudzrsn0e9uixlowfcfodffs3h4bhk # ... # u2jscwcjat4dh8xhfdkgtyg+acrb75+pvgw7jpg3311n8suuf2eq3rwocdvz # uhd+tlunmqrw7ifpkhtl1po6ka/+g6xwh00zkxl5o6abmq/fzw6/yk5yx5pr # xuwhlycn6zvgjnenwmzkhvtawthhfw== # -----end certificate-----
