![]() ![]() This is for compatibility with previous versions of OpenSSL. Read the password to derive the key from the first line of filename. If the -a option is set then base64 process the data on one line. If decryption is set then the input data is base64 decoded before being decrypted. This means that if encryption is taking place the data is base64 encoded after encryption. For more information about the format of arg see “Pass Phrase Options” in openssl(1).Įncrypt the input data: this is the default.īase64 process the data. The output filename, standard output by default. The input filename, standard input by default. Base64 encoding or decoding can also be performed either by itself or in addition to the encryption or decryption.Īlias of -list to display all supported ciphers. The symmetric cipher commands allow data to be encrypted or decrypted using various block and stream ciphers using keys based on passwords or explicitly provided. More information in Wikipedia.Openssl-enc, enc - symmetric cipher routines For this reason it is not recommended to use encryption for the transmission of confidential data. It is important to remember that encoding is not similar to encryption, and one can easily reveal the encoded data. This is how you can use base64 to encode and decode a string or a file from the terminal. The following command will decode the encoded text and save the original text in a file called " decodedfile.txtWhich can be viewed later using the command cat:īase64 -d archivoCodificado.txt > archivoDecodificado.txt We will also be able to save decoded output to file, rather than printing to standard output. This command will decode the base64 encoded text file and print the original text on standard output. To decode the content of the base64 encoded text file ' encodedfile. Decode the text fileįor decode an encoded text file, we will have to use the –decode or -d option. The following command will convert the text in the file using base64 and save the output to another file called " encodedfile.txt »:īase64 archivotexto.txt > archivoCodificado.txtįor view the content of the encoded file, we can use the command cat. This command will encode the specified text file and print its encoded form to standard output.Īs well we can save the encoded output to a file, rather than printing it to standard output. If we were interested in encoding a text file called ' archivotext.txt', the command to use would be: The command base64 can also be used to encode a text file. txt"Įcho “4oCcdGV4dG8gZGUgZWplbXBsb+KAnQo=” | base64 -decode > archivoDecodificado.txtįor view the content of the decoded file, we can use the command cat. The following command will decode the encoded text and save the original text in a file called " Decoded file. This command will print the original text to standard output as shown in the above screenshot. ![]() To decode base64 encoded text ' 4oCcdGV4dG8gZGUgZWplbXBsb + KAnQo =', the command would be:Įcho “4oCcdGV4dG8gZGUgZWplbXBsb+KAnQo=” | base64 -decode ![]() We can decode base64 encoded text using –decode or -d option. The following command will encode the text and save the output to a file called " encodedfile.txt«:Įcho “texto de ejemplo” | base64 > archivoCodificado.txtįor view the content of the encoded file, we can use the command cat, as you can see in the previous capture. We can also save the encoded output to a file, instead of printing it to standard output. This command will encode the text in the string using base64 and print the encoded text to standard output. ![]()
