OpenSSL one line base64 input. error reading input file

Question

I have AES-encrypted file, which encoded to base64 one-line string (without breaklines) and need to decrypt it. Here it is.

But when i use:

openssl enc -d -a -aes-256-cbc -in encrypted -out decrypted

OpenSSL throws "error reading input file"
But base64 util decrypts it like a charm:

base64 -d encrypted | openssl enc -d -aes-256-cbc > decrypted

Trying to find find the cause and convert to one-line base64 file:

base64 -w 0 aesfile | openssl enc -d -a -aes-256-cbc > decrypted
# error reading input file

base64 aesfile | openssl enc -d -a -aes-256-cbc > decrypted
# no errors, file decrypted

Conclusion: OpenSSL can't decode non-multiline base64 inputs

Answer 1

Encrypt

openssl enc -aes-256-cbc -pass pass:YOURPASSWORD -p -in msg.txt -out enc.txt -base64

Decrypt

openssl enc -aes-256-cbc -base64 -pass pass:YOURPASSWORD -d -p -in enc.txt -out dec.txt

If there's no newline in the encrypted file after the base64 line, you get an error saying error reading input file.
