openssl

• Certificados, certificaciones, Entidades de Certificación
• https://www.sslshopper.com/article-most-common-openssl-commands.html

• Remove a passphrase from a private key:

  openssl rsa -in privateKey.pem -out newPrivateKey.pem

• Check a Certificate Signing Request (CSR):

  openssl req -text -noout -verify -in CSR.csr

• Check a private key:

  openssl rsa -in privateKey.key -check

• Check a certificate:

  openssl x509 -in certificate.crt -text -noout

• Check a PKCS#12 file (.pfx or .p12):

  openssl pkcs12 -info -in keyStore.p12

• Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key:

  openssl x509 -noout -modulus -in certificate.crt | openssl md5
  openssl rsa -noout -modulus -in privateKey.key | openssl md5
  openssl req -noout -modulus -in CSR.csr | openssl md5

• Convert a DER file (.crt .cer .der) to PEM:

  openssl x509 -inform der -in certificate.cer -out certificate.pem

• Convert a PEM file to DER:

  openssl x509 -outform der -in certificate.pem -out certificate.der

• Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM:

  openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes

• Convert a PEM certificate file and a private key to PKCS#12 (.pfx .p12):

  openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt -certfile CACert.crt

verificar dades del certificat:

openssl pkcs12 -in certificado.pfx -nokeys | openssl x509 -noout -enddate

openssl pkcs12 -in certificado.pfx -nokeys | openssl x509 -noout -dates

openssl pkcs12 -in certificado.pfx -nokeys | openssl x509 -noout -text
