Otra manera es descomprimir flags.zip donde se encuentra las soluciones y el codigo del programa. Ademas de una version del mismo ya compilada para dar las soluciones directamente\r\n\r\n----\r\n\r\nPara comprobar los hash's obtenidos use ```solution.elf```:\r\n```bash\r\n┌──(desmon㉿DESKTOP-1GKF8CS)-[/mnt/c/Users/Desmon0x90/Desktop/Reto_ReverC_ASM]\r\n└─$ ./solution.elf\r\nModo de uso:\r\n./solution.elf \u003c1/2/3/4\u003e \u003chash md5 obtenido\u003e\r\n\u003c1/2/3/4\u003e es el numeo del hash obtenido, 1 para hash1 y consecutivamente.\r\n\u003chash md5 obtenido\u003e sera el hash que usted obtuvo.\r\n```\r\n\r\n----\r\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdesmonhak%2Freto_reverc_asm","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdesmonhak%2Freto_reverc_asm","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdesmonhak%2Freto_reverc_asm/lists"}
